Multiple IF statements to determine a match and assign value - excel

I am running a small study that basically needs to match suitable people into pairs and assign them a pair number, so each can be assigned into group A or B.
They basically need to be from the same Medical Clinic, same gender, and either below 80, or 80+ years of age.
I'm not sure if this is even possible with excel, but basically I have a sheet with a form that you enter the new participants information. I need a formula that basically checks these 3 criteria against previous entries to find someone who matches on all 3, then assign the same pair number. If it can't find a suitable match, it needs to assign a new pair number.
In the above sample data set, I want I3 to realise that C3, D3 and E3 all match C2, D2 and E2, then put a 1 in I3.
Then for I4, it would assign a 2 as it doesn't match any entries above it. Same for I5. Then I6 would realise the match in I4 and put a 2.
Not sure if this makes sense. Also there can't be more than 2 of each pair #, but I can deal with that after I am able to get the numbers generating.

If you can change column D to Age group, (71-80, 81-90 etc.) the following formula would do what you want as a first step (more than 2 people grouped together). Paste the following formula in I3 and hit cntrl+shift+enter as it is a array formula. Copy it down to other cells below.
=IFERROR(INDEX(F$1:F2,MATCH(C3&D3&E3,C$1:C2&D$1:D2&E$1:E2,0)),MAX(F$2:F2)+1)
This matches a combination of strings in columns C, D and E in the current row to array of string combination in previous rows and assigns the same Pair number, if there is no match it gets the next new number.
Try this modified formula (array formula) to not put more than two entries in a group. I have created another column G which is G2 = C2&D2&E2
=IF(COUNTIF(G$1:G2,G3)<2,IFERROR(INDEX(F$1:F2,MATCH(C3&D3&E3,C$1:C2&D$1:D2&E$1:E2,0)),MAX(F$2:F2)+1),MAX(F$2:F2)+1)

This response expands on your original requirements by returning the actual PT ID numbers of the matched pairs as well as a unique 'paired group' identifier.
The original criteria age brackets (e.g. 70-80, 81+) are used and no matched pair is used more than once.
If you already have a match from further up the data then you will want to return the paired PT ID. A simple INDEX/MATCH function pair can do that. If a match has not already been made then the IFERROR function can pass processing over to a nested INDEX function that uses the AGGREGATE¹ function rather then MATCH to return the appropriate row number.
AGGREGATE is used with its SMALL sub-function. This allows the COUNTIFS function to increment to the second, third, etc. pairing by examining the matches³ made previously.
With expanded sample data the formula in I2:K2 are,
'formula for I2
=IFERROR(IFERROR(INDEX(B$1:B1, MATCH(B2, I$1:I1, 0)),
INDEX(B:B, AGGREGATE(15, 6, ROW(B$1:INDEX(B:B, MATCH(1E+99, B:B)))/
((B:B<>B2)*(C:C=C2)*(E:E=E2)*IF(D2>80, D:D>80, (D:D>=70)*(D:D<=80))),
COUNTIFS(C$1:C1, C2, E$1:E1, E2, D$1:D1, IF(D2>80, ">80", ">=70"), D$1:D1, IF(D2>80, ">80", "<=80"))+1))),
"NO MATCH")
'formula for J2
=IFERROR(INDEX(J$1:J1, MATCH(I2, B$1:B1, 0)), MAX(J$1:J1)+1)
'formula for K2 (volatile and random - see footnote ⁴)
=IFERROR(IF(INDEX(K$1:K1, MATCH(J2, J$1:J1, 0))="A", "B", "A"), IF(ISNUMBER(I2), CHAR(RANDBETWEEN(65, 66)), ""))
Fill down as necessary.
 
¹ The AGGREGATE function was introduced with Excel 2010. It is not available in earlier versions.
² While AGGREGATE-based formulas are entered as conventional formulas (i.e. without CSE), AGGREGATE does apply cyclic array-style processing. Try and reduce your full-column references to ranges more closely representing the extents of your actual data. Array processing chews up calculation cycles logarithmically so it is good practise to narrow the referenced ranges to a minimum. See Guidelines and examples of array formulas for more information.
³ Your original narrative stated '... either between 70 and 80 or above 80 years of age.' while your subsequent comment stated 'Under 80 or 80+'. These are not the same thing. I've used the former original description since you never edited the question for clarification.
⁴ The formula destined for K2 is volatile and uses the RANDBETWEEN function. Once you are happy with the results, use Copy, Paste Special, Values to revert the formula to its underlying values. Leaving the formula intact with RANDBETWEEN means the values could change with any change throughout the workbook. Only the initial A/B value for each matched pair is random; the match in the pair will always be the A or B counterpart.

First, you can create a new column (J) that concatenates the 3 values you are comparing, you can do this with a formula like this:
=C2&IF(D2>80,"YES","NO")&D3
The you can fill I2 with a formula that checks is the concatenated value repeats in the data set with a fomula like this:
=COUNTIFS($J$2:$J$6,J2)>1

Numbering Based on Condition(s)

I'm trying to create auto numbering for Agents that are currently present and has numbers including zeroes 0 in 3rd or 4th column(zero meaning they don't get any stats but they are present)
Agents who has TEXT Value in the 3rd or 4th column are those who are not present (Ex: A = Absent, SL = Sick Leave, VL = Vacation Leave). Meaning, they should not be counted, therefore their value on 1st column should be blank, and therefore this should not stop the auto numbering for the rest of the agents below and should continue the count in sequence.
Can anyone help create formula that would fill the numbers on the 1st column automatically for those agents that are present and has value including 0 on column 3 or 4 (stats 1 or stats 2)?
To give more idea, I'm trying to show the current total number of agents who are currently present in this situation and will count their stats, and exclude all other agents who are not present and should not be counted.
Thank you!
Sequence Two Numeric Columns
Single Cell
In cell A3, a basic not spilling formula would be...
=IF(AND(ISNUMBER(C3),ISNUMBER(D3)),MAX(A$2:A2)+1,"")
... with the condition of a string in cell A2.
Without any conditions, you could try an improved version, similar to one of David Leal's suggestions:
=IF(AND(ISNUMBER(C3),ISNUMBER(D3)),
SUM(ISNUMBER(C$3:C3)*ISNUMBER(D$3:D3)),"")
Spill
In cell A3 you could use the following:
=LET(Data1,C3:C13,Data2,D3:D13,
Data,ISNUMBER(Data1)*ISNUMBER(Data2),
IFERROR(SCAN(0,Data,LAMBDA(a,b,a+b))/Data,""))
Line1: the inputs ('constants'), the same-sized single-column ranges
Line2: the zeros and ones, where the ones present the data of interest
Line3: the formula to replace the ones with the sequence and the zeros (errors due to division by zero) with an empty string
Converted to a LAMBDA, it could look like the following:
=LAMBDA(Data1,Data2,LET(
Data,ISNUMBER(Data1)*ISNUMBER(Data2),
IFERROR(SCAN(0,Data,LAMBDA(a,b,a+b))/Data,"")))(C3:C13,D3:D13)
Since it's such a long formula, you could create your own Lambda function by using this part...
=LAMBDA(Data1,Data2,LET(
Data,ISNUMBER(Data1)*ISNUMBER(Data2),
IFERROR(SCAN(0,Data,LAMBDA(a,b,a+b))/Data,"")))
... to define a name, e.g. SeqNumeric, when in the same cell, you could use
it simply with...
=SeqNumeric(C3:C13,D3:D13)
... instead.
Now you can use the function like any other Excel function anywhere in the workbook.
The Path
F3 =ISNUMBER(C3:C13)*ISNUMBER(D3:D13) - multiply: zeros-no, ones-yes
G3 =SCAN(0,F3#,LAMBDA(a,b,a+b)) - use the 'LAMBDA' helper function 'SCAN'
H3 =G3#/F3# - divide the 'scan' result by the zeros and ones
I3 =IFERROR(H3#,"") - convert the '#DIV/0!' errors to empty strings
The translation of the SCAN part could be something like the following:
Set the initial result a to 0.
Create a new array of the size of the initial array in F3#.
Loop through each element of the initial array, write its value to b, and replace a with the sum of a+b.
Write (the accumulated) a to the current element of the new array and repeat for the remaining elements of either array.
Return the new array.
Combine all of it in a LET.
J3 =LET(Data1,C3:C13,Data2,D3:D13,
Data,ISNUMBER(Data1)*ISNUMBER(Data2),
IFERROR(SCAN(0,Data,LAMBDA(a,b,a+b))/Data,""))
Convert to LAMBDA.
K3 =LAMBDA(Data1,Data2,LET(
Data,ISNUMBER(Data1)*ISNUMBER(Data2),
IFERROR(SCAN(0,Data,LAMBDA(a,b,a+b))/Data,"")))(C3:C13,D3:D13)
Copy the first part of the LAMBDA (note how it results in a #CALC! error since no parameters are supplied)...
L3 =LAMBDA(Data1,Data2,LET(
Data,ISNUMBER(Data1)*ISNUMBER(Data2),
IFERROR(SCAN(0,Data,LAMBDA(a,b,a+b))/Data,"")))
... and select Formulas -> Name Manager -> New to create your own function and finally use it with the following:
A3 =SeqNumeric(C3:C13,D3:D13)
You can try the following in cell A1:
=LET(B, B2:B12, C, C2:C12, f, 1*ISNUMBER(B*C),seq, SEQUENCE(ROWS(B)),
MAP(seq, LAMBDA(s, IF(INDEX(f,s)=0, "",SUM(FILTER(f, (seq<=s),0))))))
Here is the output:
A non-array version, expanding down the formula would be:
=IF(ISNUMBER(B2*C2), SUM(1*ISNUMBER(B$2:B2*C$2:C2)),"")
For the array version, it counts only if both columns Stat1 and Stat2 are numeric. The name f, has a value of 1 if the condition is TRUE, otherwise is 0. The MAP does the count if the index position of the f array is not zero, otherwise returns an empty string.
I think I got it.
This is the formula that I made
=IF(COUNTIFS(D2:BE2,"*",$D$1:$BE$1,TODAY())>0,"",MAX(A1:A$4)+1)
Countif criteria 1 = if the cell contains a letter and is counted > 0 then it will return blank, otherwise it will start the count using max function. The countif criteria 2 will will return the correct value according to the date today since the excel sheet has several data daily.

Three Dimensional Lookup Using INDEX/MATCH

This was taken and improved slightly from Question that has since been deleted
For those who can see deleted posts, it was taken from here: https://stackoverflow.com/questions/39793322/three-dimensional-lookup-no-concatenate-or-named-ranges-excel
I'm trying to do a three dimensional lookup without named ranges or concatenates. Simplified, my data is on the form:
Column1 Column2 Column3
Scott
P 1 2 3
M 4 5 6
N 7 8 9
George
P 10 11 12
M 13 14 15
N 16 17 18
I now want to search for a specific Name and then for a specific letter within that names table, I then want to match this row number with a specific column.
I tried a simple INDEX/MATCH:
=INDEX(A:D,MATCH("M",A:A,0),MATCH("Column1",1:1,0))
And that works for the fist name but not any others as it finds the first instance of M.
How do I modify it to look for a different name?
I have answered below, but want to see if someone has a better solution.
I used an IF() statement array formula to find what the P row number was after the George row... I also needed to use the MIN() function to get the first P row number after the name.
Beyond that, it's a simple INDEX() function.... that racked my brain for over an hour :).
=INDEX($A$1:$D$9,MIN(IF((ROW(A1:A9)>MATCH($F$4,A1:A9,0))*(A1:A9=$F$5),ROW(A1:A9),"")),MATCH($F$6,$A$1:$D$1,0))
Don't Forget!
Use Ctrl+Shift+Enter when finishing the formula, so it gets evaluated as an array formula.
You can use two other INDEX/MATCH's inside the first MATCH to set the lookup range. Then you simply need to add the MATCH() to find the absolute position of the name.
=INDEX(A:D,MATCH($H$4,INDEX(A:A,MATCH($H$3,A:A,0)):INDEX(A:A,MATCH($H$3,A:A,0)+4),0)+MATCH($H$3,A:A,0)-1,MATCH($H$5,$1:$1,0))
This one works better and does not have a size constraint:
=INDEX(A:D,MATCH(F4,INDEX(A:A,MATCH(F3,A:A,0)):A1040000,0)+MATCH(F3,A:A,0)-1,MATCH(F5,A1:D1,0))
You can do this just by adding the results of two matches together. One match for the names plus one match for the letter equals the total row.
=INDEX(A:D,MATCH(G5,A3:A5,0)+MATCH(G3,A:A,0),MATCH(G4,1:1,0))
In other words: Index(All of the Data, Match(Name, In name column, exact) + Match(Letter, In letter column, exact), Match(Column name, in Column row, exact)
Screen capture of working sheet
My answer attempts the general case with only one caveat:
That a letter is single character text, and a name is more than 1 character. Otherwise i feel there is no difference logically between letters and names, and it is then impossible to really do...
RE-EDIT for better function construction:
{=INDEX($A$1:$D$17, MATCH($H$3,$A1:$A17, 0)+MATCH($H$4, INDEX($A1:$A17, MATCH($H$3,$A1:$A17, 0)):INDEX($A:$A, SMALL(IFERROR(MATCH($H$3,$A1:$A17, 0)+POWER(SQRT(IF(LEN($A$1:$A$17)>1, ROW($A$1:$A$17), 0)-MATCH($H$3,$A$1:$A$17, 0)), 2)-1, ROWS($A$1:$A$17)), 2)), 0)-1, MATCH($H$5, $A$1:$D$1, 0))}
This uses an array formula along column A, and checks if the length is > 1 and throws the row nums into an array, with letters given a 0.
Then match row of unique name(e.g. George) is subtracted from each.
We then use a min(of all other name rows, with the last data row as the final default - SMALL function with 2 parameter) to find the next name row(or last data row if there is no following name).
Rest is standard index/match etc.
It will correctly return #N/A if there is no such letter under the chosen name...
My dataset is A1:A17, and the formula could use A:A instead each time, but the array calc inside the IF needs the A1:A17 for speed.
EDIT for better function construction:
If we wanted to avoid editing the formula when the data length changes, then we could let full column references of A:A go through the entire construction(and lose speed/efficiency) with the last data row in colA calculated via ROWS(A:A):
Re-edit:
{=INDEX($A:$D, MATCH($H$3,$A:$A, 0)+MATCH($H$4, INDEX($A:$A, MATCH($H$3,$A:$A, 0)):INDEX($A:$A, SMALL(IFERROR(MATCH($H$3,$A:$A, 0)+POWER(SQRT(IF(LEN($A:$A)>1, ROW($A:$A), 0)-MATCH($H$3,$A:$A, 0)), 2)-1, ROWS($A:$A)), 2)), 0)-1, MATCH($H$5,1:1, 0))}
It really depends on the setup...
Edit again for version which takes blanks as separators for names
If you want to use blanks as the separator for names, where no blanks are in the data results, but blanks appear in columns B to D where there is a name, then a tiny change in the above formulae will result in this:
=INDEX($A$1:$D$17, MATCH($H$3,$A$1:$A$17, 0)+MATCH($H$4, INDEX($A:$A, MATCH($H$3,$A:$A, 0)):INDEX($A:$A, SMALL(IFERROR(MATCH($H$3,$A:$A, 0)+POWER(SQRT(IF($B$1:$B$17="", ROW($A$1:$A$17), 0)-MATCH($H$3,$A$1:$A$17, 0)), 2)-1, ROWS($A$1:$A$17)), 2)), 0)-1, MATCH($H$5, $A$1:$D$1, 0))
This means that the names and letters do not have to be any specified length, but just one proviso is that blanks appear in the row with the name.
A small amendment to the condition to find the end range to search for the letter by replacing this: SQRT(IF(LEN($A$1:$A$17)>1, with this:
SQRT(IF($B$1:$B$17="",
I would use the area (4th parameter) of Index(). Below is a screenshot of test data. This example assumes the same columns and keys are sorted and consistent.
This works by using (Range1,Range2) as the first parameter of index. For the 4th parameter of index, use N for which area in the () you want Index to return.
I think this may be slightly tidier, and a little easier to modify maybe.
=INDEX(OFFSET(INDIRECT("A"&MATCH($H$3,$A:$A,0),TRUE),0,0,4,4),MATCH($H$4,$A:$A,0),MATCH(H5,$1:$1,0))
Using offset to create the range first, we're able to use the name from H3 to set that up, and then beyond that we are just indexing within that new range.
Now this is still dependendent on staying in Column A for the names.
Assuming the format of the data is always Name then P, M and N this formula does the work:
=INDEX($A:$D,
MATCH($H$3,$A:$A,0)
+LOOKUP($H$4,{"P",1;"M",2;"N",3}),
MATCH($H$5,$1:$1,0))
This solution works on almost all conditions. One restriction I found is when one of the subjects (Names) does no have data for any of the details (letters), but as of now the same occurs with all the other answers.
The formula assumes the data is located at B6:F30 (in order to ensure it can be applied regardless of the source range location).
The formula uses the Index\Match functions:
First, a MATCH to retrieve the position of the Name:
MATCH($H8,$B$6:$B$30,0)
With that info it uses INDEX to build a range that is used to obtain the position of the Detail (letter) using a second MATCH Function:
+ MATCH($I8,INDEX($B$6:$B$30, 1 + MATCH($H8,$B$6:$B$30,0))
:INDEX($B$6:$B$30,ROWS($B$6:$B$30)),0),
Adding the results of the first and second MATCH functions obtains the position of the Name`Detail` combination and uses it in an Index to the entire data. The position of the Data Column required is obtained with a Match:
INDEX($B$6:$F$30, 1st.MATCH + 2nd.MATCH,
MATCH(J$6,$B$6:$F$6,0))
With the results located at G6:L30 enter this formula in J8 then copy to J8:L30:
= INDEX( $B$6:$F$30,
MATCH( $H8, $B$6:$B$30, 0)
+MATCH( $I8, INDEX( $B$6:$B$30 , 1 + MATCH( $H8, $B$6:$B$30 ,0))
: INDEX( $B$6:$B$30, ROWS($B$6:$B$30) ),0),
MATCH( J$6, $B$6:$F$6, 0)),"")
This solution works in all conditions discussed so far (let me know of any condition that it does not work and I’ll try to cover it).
I’m posting this as a separated answer as the formulas applied in prior answer rightly apply to the conditions stated in them, as such they will be useful to users with those specific scenarios, so they don’t need to apply these long formulas.
This formula assumes the data is located at B6:E30 (in order to ensure it can be applied regardless of the source range location).
This formula uses the Index\Match functions and it’s a Formula Array.
FormulaArrays are entered pressing [Ctrl] + [Shift] + [Enter] simultaneously, you shall see { and } around the formula if entered correctly
Syntax:
=IFERROR(INDEX(DataRng,
MATCH(Value1,NamesRng,0)
+IFERROR(MATCH(Value2,INDEX(NamesRng,
1+MATCH(Value1,NamesRng,0))
:INDEX(NamesRng, IFERROR(MATCH(Value1,NamesRng,0)
+MATCH("#",IF((INDEX(Col1Rng,1+MATCH(Value1,NamesRng,0))
:INDEX(Col1Rng,ROWS(NamesRng)))="","#","!"),0),
ROWS(NamesRng))),0),NA()),MATCH(ValCol,DataHdr,0)),"")
Arguments:
Assuming the data is located at B6:E30.
Value1= Name to be found in Data, i.e. George, Scott, etc.
Value2= Detail to be found in Data, i.e. Detail1, Detalle2, etc.
ValCol = Column to be found in Data i.e. Column1, Column2, etc.
DataRng= $B$6:$E$30
DataHdr= $B$6:$E$6
NamesRng= $B$6:$B$30
Col1Rng= $C$6:$C$30
1st MATCH: Retrieves the position of the Name:
MATCH(Value1,NamesRng,0)
2nd MATCH: Retrieves the end position of the Name’s corresponding Details, which is determined by a blank value in column C or the end of the data range:
MATCH("#",IF((INDEX(Col1Rng, 1 + 1stMATCH)
:INDEX(Col1Rng,ROWS(NamesRng)))="","#","!"),0),
Builds a Range (vRange): With the Names's Details using the 1st and 2nd match functions. If 2nd Match returns an error then it uses the last row of the Data range:
INDEX(NamesRng, 1 + 1stMATCH )
:INDEX(NamesRng, IFERROR( 1stMATCH + 2ndMATCH, ROWS(NamesRng)))
3rd MATCH: Retrieves the position of the Detail within the vRange. It returns #NA if the combination is not present.
IFERROR(MATCH(Value2, vRange,0), NA())
Adding the results of the 1st and 3rd match functions obtains the Row index of the Name`Detailcombination or#NAif no found.
The Column index is obtained with a Match from the Header of the Data.
It then applying the INDEX function to the Data Range returns the value of theName\Detail\Columncombination.
If theName\Detail` combination is not found it returns blank.
=IFERROR( INDEX( DataRng, 1stMATCH + 3rdMATCH, MATCH(Column,DataHdr,0)),"")
With the results located at H6:L37 enter this Formula Array in J8 then copy to K8:L37 and to J9:L37:
=IFERROR( INDEX($B$6:$E$30,
MATCH($H8,$B$6:$B$30,0)
+IFERROR( MATCH($I8, INDEX($B$6:$B$30,
1+MATCH($H8,$B$6:$B$30,0))
:INDEX($B$6:$B$30, IFERROR(MATCH($H8,$B$6:$B$30,0)
+MATCH("#", IF((INDEX($C$6:$C$30,1+MATCH($H8,$B$6:$B$30,0))
:INDEX($C$6:$C$30,ROWS($B$6:$B$30)))="","#","!"),0),
ROWS($B$6:$B$30))),0),NA()),
MATCH(J$6,$B$6:$E$6,0)), "")
Wow... So many solutions already.
I think a simpler solution could be using offset to get a more generic answer.
=INDEX($A$1:$D$9, MATCH($G$3,OFFSET($A$1,MATCH($G$2,$A$1:$A$9,0),0,3,1),0)+MATCH($G$2,$A$1:$A$9,0), MATCH($G$4,$B$1:$D$1,0)+1)
The only variable to look for is 3 which is the number of M/N/P options present because that will affect the number of rows. Otherwise, the solution works fine in all possible scenarios and different orders.
When I have more than two inpunts for a data search I prefer to have the data organized as shown in the figure, so that I can use a pivot table and get it to organize the data in rows and columns as I like.
Then I use GETPIVOTDATA to search for a value.
Cell G9 contains this formula:
=GETPIVOTDATA("Value";$F$3;"Name";G15;"Letter";G16;"Column";G17)

Returning all possible values instead of a VLOOKUP

So I've looked up tutorials on how to do this, and I'm still struggling, so I could use some expert help. I know it involves a very complex nested formula with things like SMALL, ROW, INDEX, etc...
So here are two screenshots that provide a sample of what I'm looking for. In realities there is over 1000 rows, but this makes it easier for you guys.
So here is my first example, lets call this Sheet1!:
Code, ID_1 and ID_2. So as you can see (and just focus on the input in A2) there will be two separate IDs in the linked workbook. That sheet, or at least a tiny sample of it, looks like this:
In the first column we see the code we're looking for (which is what we have in A2 of the first one), each of them with different IDs. So as I'm sure you can tell by now, I'm looking for a formula that will allow me to return those values in ID_1 and ID_2 in the first sheet.
I have been going at this for an hour and I'm stumped, so I would greatly appreciate any help provided!
This is a more generic code if the ids are NOT listed consecutively: Obviously I have done this as an example to take in a more general case where the ids occur anywhere throughout the second dataset, AND where there are potentially several.
IFERROR(INDEX($V$2:$V$15, SMALL(IF($U$2:$U$15=$M2, ROW($U$2:$U$15), FALSE), COLUMNS($N2:N2))-ROW($V$1), 1), "")
This formula must be entered with Ctrl-Shift-Enter before copying across and down! Note all absolute and relative referencing/locking ($ signs)
The logical steps in constructing such a formula:
1) We use IF function to test if the values in the column U match the value in column M.
2) In the 'value-if-true' parameter, we will get the corresponding row number of values in column U. These numbers will be fed later in the SMALL function.
3) In the value-if-false part, we just return false, as that will later be used as a non-number in the SMALL function
Above 3 steps in the part: IF($U$2:$U$15=$M2, ROW($U$2:$U$15), FALSE)
4 ) We have now an array of mixed row numbers and FALSE values, which we want to feed to the INDEX function to simply get the corresponding value in column V(our second datset). BUT as we wish to retrieve the different row matches for each code, we have to fish them out of the mixed array with the SMALL function.
5) using our columns as an incrementer, we apply the SMALL function to the array with a varying k parameter. We USE the COLUMNS function (note carefully the different $ sign usage), so that as we drag the formula across, the column count increments: COLUMNS($N2:N2) - giving K values of 1, 2, 3, 4 as we drag the formula across from column N to column Q. Note that it is useful that the SMALL function disregards FALSE values when looking through the array for the values by size.
6) There is an adjustment to account for the fact that the rows are relative to the 'Ids' range which we will feed into the INDEX function to retrieve the different ids. SMALL(IF($U$2:$U$15=$M2, ROW($U$2:$U$15), FALSE), COLUMNS($N2:N2))-ROW($V$1).
This can be avoided if we use the entire column V as the look-up array parameter in the INDEX function, but that's another way...
7) This resulting value can now be passed to the INDEX function to obtain the various ids. The column_num parameter of 1 which I put in the function isn't necessary in a single-column look-up array, but is there for completeness.
8) The entire construction is then wrapped in an IFERROR function to give an empty string if there is no match, but some people may wish to have error outputs there...
well if the two ID will be consecutive in the second list try this:
=index('workbookname'SheetName!columnrangeofserialnumbers,match(A2,'workbookname'Sheetname!columnrangeofIDs,0))
Assuming your other workbook is called Serials, and all the info is on sheet1 you would enter the follow in B2:
=index('serials'sheet1!$B$2:$B$1000,match(A2,'serials'sheet1!$B$2:$B$1000,0))
in C2 enter the following (assuming ids will show up consecutively)
=index('serials'sheet1!$B$2:$B$1000,match(A2,'serials'sheet1!$B$2:$B$1000,0)+1)
This only works if the other workbook is open as far as I know and with the understanding that the two ID will be listed consecutively in the list.

Is there a 2 Value Look up function in MS Excel that can perform the following?

I am going crazy over this. It seems so simple yet I can't figure this out. I have two worksheets. First worksheet is my data. Second is like an answer key. Upon checking checking, A1:B1 in Sheet 1 is a match with the conditions in Row 52 in SHEET 2, therefore, the value in Column C is "MGC". What is the formula that will perform this function? It's really hard to explain without the data so I pasted a link of the sample spreadsheet. Thank you so much in advance.
sample spreadsheet here. https://docs.google.com/spreadsheets/d/1_AjuNfCdGfEM-XkqPa6W4hSIxQg4NM2Vg4c2C1pQ_vQ/edit?usp=sharing

In Sheet2, insert a column in front of Column A and put the formula in A2 =C2&D2.
Then in Sheet1, Cell C2 the formula =vlookup(A2&B2,Sheet2!A:B,2,0).
the first make a concatenated key to lookup, then the second looks up that key.
How about a index(match())? If I've understood correctly you need to match across both the A and B column in sheet one, checking for the relevant values in B and C on sheet 2 to retrun worksheet 2 column a to worksheet 1 column c.
third version try:
=INDEX(Sheet2!$C$1:$C$360,MATCH(Sheet1!A1&Sheet1!B1,Sheet2!$B$1:$B$360&Sheet2!$C$1:$C$360,0))
Basically what this does is use concatenation, the & operator, to specify you are looking for "Criteria A" & "Criteria B" in sheet 1, which makes the string "Criteria A Criteria B", which is supplied in the first part of the match function.
In the second it then says match this against all of my variables in sheet 2 in the same way with concantenation.
The final part of match function (0) specifies you want an 'exact' match
It then supplied this as a reference to the index function, which then finds the row intersecting with the value you want, and returns that.
As noted here https://support.microsoft.com/en-us/kb/59482 this is an array formula, so it behaves differently, and must be input differently. https://support.office.com/en-za/article/Guidelines-and-examples-of-array-formulas-7d94a64e-3ff3-4686-9372-ecfd5caa57c7
There are (at least) 2 ways you could do this without VBA.
USING A SORTED LIST
The first relies on the assumption that your data can be re-sorted, so that everything "Unreported" is in the top, and everything "reported" is together below that (or vice versa). Assuming that this is the case (and it appears to already be sorted like this),we will use the function OFFSET to create a new range which shows only the values that align with either being "Unreported" or "Reported".
Offset takes a given reference to a point on a sheet, and then moves down/up & left/right to see what reference you want to return. Then, it returns a range of cells of a given height, and a given width. Here, we will want to start on Sheet2 at the top left, moving down until we find the term "Unreported" or "Reported". Once that term is found, we will want to move one column to the right (to pull column B from sheet 2), and then have a 'height' of as many rows as there are "unreported" or "reported" cells. This will look as follows in A1 on sheet 1, copied down:
=OFFSET(Sheet2!$A$1,MATCH(A1,Sheet2!A:A,0)-1,1,COUNTIF(Sheet2!A:A,A1),1)
This says: First, start at cell A1 on sheet2. Then find the term in A1 (either "unreported" or "reported", on sheet2!A:A (we subtract 1 because OFFSET starts at A1 - so if your data starts at A1 we need to actually stay at "0". If you have headers on sheet2, you will not need this -1). Then, move 1 column to the right. Go down the rows for as many times as Sheet2 column A has the term found in Sheet1 A1. Stay 1 column wide. Together, this will leave you with a single range on sheet2, showing column B for the entire length that column A matches your term in sheet1 A1.
Now we need to take that OFFSET, and use it to find out when the term in Sheet1 B1 is matched in Sheet2 column B. This will work as follows:
=MATCH(B1,[FORMULA ABOVE],0)
This shows the number of rows down, starting at the special OFFSET array created above, that the term from B1 is matched in column B from sheet2. To use this information to pull the result from column C on sheet 2, we can use the INDEX function, like so:
=INDEX([FORMULA ABOVE],MATCH(B1,[FORMULA ABOVE],0))
Because this would be fairly convoluted to have in a single cell, we can simplify this by using VLOOKUP, which will only require the OFFSET function to be entered a single time. This will work as follows:
=VLOOKUP(B1,[FORMULA ABOVE],2,0)
This takes the OFFSET formula above, finds the matching term in B1, and moves to the 2nd column to get the value from column C in sheet2. Because we are going to use VLOOKUP, the offset formula above will need to be adjusted to provide 2 columns of data instead of 1. Together, this will look as follows:
FINAL FORMULA FOR SHEET1, C1 & COPIED DOWN
=VLOOKUP(B1,OFFSET(Sheet2!$A$1,MATCH(A1,Sheet2!A:A,0)-1,1,COUNTIF(Sheet2!A:A,A1),2),2,0)
OPTION USING ARRAY FORMULAS
The above method will only work if your data is sorted so that the REPORTED and UNREPORTED rows are grouped together. If they cannot be sorted, you can use an ARRAY FORMULA, which essentially takes a formula which would normal apply to a single cell, and runs it over an entire range of cells. It returns an array of results, which must be reduced down to a single value. A basic array formula looks like this [assume for this example that A1 = 1, A2 = 2...A5 = 5]:
=IF(A1:A5>3,A1:A5,"")
Confirm this (and all array functions) by pressing CTRL + SHIFT + ENTER, instead of just ENTER. This looks at each cell from A1:A5, and if the value is bigger than 3, it gives the number from that cell - otherwise, it returns "". In this case, the result would be the array {"";"";"";4;5}. To get the single total of 9, wrap that in a SUM function:
=SUM(IF(A1:A5>3,A1:A5,""))
In your case, we will want to use an array formula to see what row in Sheet2 matches A1 from Sheet1, and B1 from Sheet1. This will look like this:
=IF(Sheet2!$A$1:A$100=A1,IF(Sheet2!$B$1:$B$100,ROW($B$1:$B$100),""),"")
This checks which rows in column A from sheet 2 match A1. For those that do, it then checks which rows in column B from sheet 2 match B1. For those, it pulls the row number from that match. Everything else returns "". Assuming no duplicates, there should only 1 row number which gets returned. To pull that number from the array of results, wrap the whole thing in a MATCH function. Now that you have the row number, you can use an INDEX function to pull the result in Column C with that row, like this:
FINAL ARRAY FORMULA METHOD
=INDEX($C$1:$C$100,MAX(IF(Sheet2!$A$1:A$100=A1,IF(Sheet2!$B$1:$B$100,ROW(Sheet2!$B$1:$B$100),""),"")))
Remember to confirm with CTRL + SHIFT + ENTER instead of just ENTER, when you type this formula. Note that I didn't refer to all of Sheet2!A:A, because array formulas run very slowly over large ranges.
The following formula should work without making any changes to the datasheets.
=INDEX(Sheet2!$A$1:$A$360,MATCH(Sheet1!A1,IF(Sheet2!$C$1:$C$360=Sheet1!B1,Sheet2!$B$1:$B$360),0))
Remember to save this formula as an array with CTRL+SHIFT+ENTER
Documentation on how to use INDEX and MATCH against multiple criteria can be found on Microsoft Support.
It's not clear what you want to do with the multiples that do not have corresponding matches. txed is listed as Unreported twice in Sheet1; kntyctap is listed as Unreported three times. There are only one corresponding match on Sheet2 for each of these.
Non-array Standard Formulas for multiple criteria matches
For Excel 2010 and above use this standard formula in Sheet1!C1:
=IFERROR(INDEX(Sheet2!$A$1:$A$999,AGGREGATE(15,6,ROW(1:999)/((Sheet2!$B$1:$B$999=A2)*(Sheet2!$C$1:$C$999=B1)), COUNTIFS(A$1:A1, A1, B$1:B1, B1))), "")
For version of Excel prior to 2010 use this standard formula in Sheet1!C1:
=IFERROR(INDEX(Sheet2!$A$1:$A$999, SMALL(INDEX(ROW($1:$999)+((Sheet2!$B$1:$B$999<>A1)+(Sheet2!$C$1:$C$999<>B1))*1E+99, , ), COUNTIFS(A$1:A1, A1, B$1:B1, B1))), "")
I've handled error with the IFERROR function in that latter formula. Excel 2003 and previous may have to use an IF(ISERROR(..., ...)) combination.

Tolerant average (ignore #NA, etc.)

I want to calculate the average over a range (B1:B12 or C1:C12 in the figure), excluding:
Cells not being numeric, including Empty strings, Blank cells with no contents, #NA, text, etc. (B1+B8:B12 or C1+C8:C12 here).
Cells for which corresponding cells in a range (A1:A12 here) have values outside an interval ([7,35] here). This would further exclude B2:B3 or C2:C3.
At this point, cells in column A may contain numbers or have no contents.
I think it is not possible to use any built-in AVERAGE-like function. Then, I tried calculating the sum, the count, and divide. I can calculate the count (F2 and F7), but not the sum (F3), when I have #N/A in the range, e.g.
How can I do this?
Notes:
Column G shows the formulas in column F.
I cannot filter and use SUBTOTAL.
B8:C8 contain Blank cells with no contents, B9:C9 contain Empty strings.
I am looking for (non-user defined) formulas, i.e., non-VBA.

Providing you are using Excel 2010 and above the AGGREGATE
function
can be optioned to ignore all errors.
=AGGREGATE(1, 6, A1:A5)
        
You can accomplish this by using array formulas based upon nested IFs to provide at least part of the criteria. When an IF resolves to FALSE it no longer process the TRUE portion of the statement.
   
The array formulas in F2:F3 are,
=SUM(IF(NOT(ISNA(B2:B13)), (A2:A13>=7)*(A2:A13<=35)*(B2:B13<>"")))
=SUM(IF(NOT(ISNA(B2:B13)), IF(B2:B13<>"", (A2:A13>=7)*(A2:A13<=35)*B2:B13)))
The array formulas in F7:F8 are,
=SUM(IF(NOT(ISNA(C2:C13)), (A2:A13>=7)*(A2:A13<=35)*(C2:C13<>"")))
=SUM(IF(NOT(ISNA(C2:C13)), IF(C2:C13<>"", (A2:A13>=7)*(A2:A13<=35)*C2:C13)))
Array formulas need to be finalized with Ctrl+Shift+Enter↵. Once entered correctly, they can be filled down like any other formula if necessary.
Array formulas increase calculation load logarithmically as the range(s) they refer to expand. Try to keep excess blank rows to a minimum and avoid full column references.
You can get the average of your "NA" column values in one fairly simple formula like this:
=AVERAGE(IF(
(
($A$2:$A$13>=$F$2)*
($A$2:$A$13<=$F$3)*
ISNUMBER(B2:B13)
)>0,
B2:B13))
entered as an array formula using CtrlShiftEnter↵.
I find this to be a very clear way of writing it, because all your conditions are lined up next to each other. They're "and'ed" using the mathematical operator *; this of course converts TRUE and FALSE values to 1's and 0's, respectively, so when the and'ing is done, I convert them back to TRUE/FALSE using >0. Note that instead of hard-coding your thresholds 7 and 35 (hard-coding literals is usually considered bad practice), I put them in cells.
Same logic for your sum and your count; just replace AVERAGE with SUM and COUNT, respectively:
=SUM(IF((($A$2:$A$13>=$F$2)*($A$2:$A$13<=$F$3)*ISNUMBER(B2:B13))>0,B2:B13))
=COUNT(IF((($A$2:$A$13>=$F$2)*($A$2:$A$13<=$F$3)*ISNUMBER(B2:B13))>0,B2:B13))
though a more succinct formula can also be used for the count:
=SUM(($A$2:$A$13>=$F$2)*($A$2:$A$13<=$F$3)*ISNUMBER(B2:B13))
The same formulas can be used to average/sum/count your "blank" column. Here I just drag-copied them one column to the right (column G), which means that all instances of B2:B13 became C2:C13.
