Looking up a value in a specified column - excel

Something I've wanted to do quite a bit lately, and can't work out how to do, is MATCH in a column I pass as an argument. Essentially, I have a two dimensional array, and I want to be able to find the first occurrence of a given value in the nth column, for any given value of n, and return the row number it occurs at. Alternatively (and more-or-less equivalently), I want to be able to search in the column with a given column header. Is there any way to do this?
Effectively, I want to simulate the non-existent function =MATCH(lookup_value,lookup_array,lookup_column,[match_type])
I've kludged together a horrible bodge job using INDIRECT, which works, but offends me horribly.
=MATCH(lookup_value,INDIRECT("R"&<top of array>&"C"&<left of array>+<column reference>&":R"&<bottom of array>&"C"&<left of array>+<column reference>,FALSE),FALSE)

This formula should work for you and will avoid INDIRECT. Anytime you can avoid using Indirect, I recommend doing so.
=MATCH(lookup_value,INDEX(lookup_array,0,MATCH(lookup_header,array_headers,0)),0)
If you aren't looking up the column by column header and just have the column number, then it becomes easier:
=MATCH(lookup_value,INDEX(lookup_array,0,column_number),0)

You could do something like this:
Set findCell = ActiveSheet.Range("A:Z").Find(What:="term_to_search")
Will select a header based on your search term.
Set range = ActiveSheet.Range(findCell, findCell.Offset(DEF_MAX_ROWS, 0))
Set up a range which will search from that header down a whole column.

For column references beyond Z you might switch notation (Excel Options, Formulas, Working with formulas and check R1C1 reference style) and, assuming the value to be looked up is in 'A1' (R1C1) with the column number in 'A2' (R2C1) apply:
=MATCH(R1C1,INDIRECT("C"&R2C1,0),0)
to save some complexity in converting a string of two or three characters into the relevant column number.

Say we have a two dimensional array: B3:E17 and we wish to locate Happiness in the third column of that array.In G1 enter:
B3:E17
In G2 enter:
3
In G3 enter:
=ADDRESS(ROW(INDIRECT(G1)),COLUMN(INDIRECT(G1))+$G$2-1) & ":" & ADDRESS(ROW(INDIRECT(G1))+ROWS(INDIRECT(G1))-1,COLUMN(INDIRECT(G1))+$G$2-1)
This will display the address of that third column. Then in G4 enter:
=MATCH("Happiness",INDIRECT(G3),0)
For example:

You can specify a range in a formula using the INDIRECT function. So, for example, if you put the letter designation for the column you want to search in cell A75, you could use:
=MATCH("Value_To_Match", INDIRECT(A75 & ":" & A75), 0)
So, if the value in A75 is G, the string built up in the INDIRECT call is G:G, and the MATCH will look through column G for "Value_To_Match" and return the row number in which it's found.
Using this idea, you can put a formula into A75 that generates the column designation for the column you want to search. For example, if your column headers are all in row 1, and the header you want to search for is in A74, you can do:
=CHAR(MATCH(A74, 1:1, 0) + 64)
using the CHAR function to convert numbers into ASCII characters, so 65 becomes A, 66 becomes B, etc. Note that this will only work if you don't have columns past Z. You'd need a more fussy formula to do the right thing with AA, etc.
You can overcome the annoyances of dealing with column letters by using R1C1 notation instead, which you can activate by adding a second parameter of FALSE to the INDIRECT expression. Now, instead of specifying your column by a letter, you'll specify it using a number. This simplifies the column-finder in A75:
=MATCH(A74, 1:1, 0)
and also the INDIRECT expression in your overall MATCH:
=MATCH("Value_To_Match", INDIRECT("C" & A75, FALSE), 0)

=ISNUMBER(SEARCH()) formula not working properly

Basically, im trying to search if values from column b is contained in cells on column a
I am currently using the formula
=ISNUMBER(SEARCH(B1,$A:$A))
and using it inside a conditional formatting to highlight the cells in column A that contains strings from column B. But it is not highlighting the correct cells
any advice?
Problem is that your ISNUMBER(SEARCH(…. formula is returning an array of values {FALSE;TRUE;FALSE;FALSE;...} one return for each item in within_text. You need to know if any of those items match.
So, with your formula, consider the array formula modification
=OR(ISNUMBER(SEARCH(B1,$A:$A)))
Since this is an array formula, you need to "confirm" it by holding down ctrl + shift while hitting enter. If you do this correctly, Excel will place braces {...} around the formula as observed in the formula bar
If you don't like to use the CSE entry method, you could use this formula which will return zero for no matches, or be non-zero for any matches:
=SUMPRODUCT(-ISNUMBER(SEARCH(B1,$A:$A)))
Excel's SEARCH function is used to find the position of one string within another string. Generally you use it like this:
=SEARCH("String A", "A Longer String Containing String A")
This will return the character index where first string starts within the second string, which in this case would be 28.
What you really need is a VLOOKUP. Since you're doing a textual search (substring), you need your range to be of text type instead of number.
You should do the following:
Add an extra column to the right of Column A and use TEXT function to convert entries to textual form:
=TEXT(A1, "#")
Now you can use VLOOKUP to perform a substring-match in this textual range. VLOOKUP supports wildcards when you do not ask it to perform an exact match (4th argument should be FALSE). Here is your formula then:
=VLOOKUP("*" & C1 & "*",$B:$B,1,FALSE)
Note that I have passed column B (textual column) as the lookup range, whereas C1 is the cell containing the text that you want to search.
This method also has the additional advantage that it returns the actual matched entry from the range so you don't have to find it manually.
Once you have your results, you can apply conditional formatting to it.
Highlight column A (or the relevant range in column A starting cell A1) with the first cell (which is A1 in this case) as the active cell, use the following formula as the conditional formatting rule:
=(SEARCH($B1,$A1)*(LEN($B1)>0))>0
The logic is to first search the given sub-string from the main string, then multiple the result by LEN($B1)>0 to exclude the result of 1 returned for blank cells in column B.
Note: Conditional Formatting works in array fashion so even though the formula only looks at values in the first row of the range, as long as you use the relative (or in some cases absolute) cell references correctly and highlight the result range correctly before setting up the rule, the rule will be applied across in the same way as for the first row of the array as demonstrated in this example.

Use VLOOKUP with split ranges

I'm making a formula that looks up a value and returns a value, fairly simple procedure as I can use VLOOKUP or INDEX-MATCH. However, I cannot seem to create or find a way to make it work when the ranges are located side by side. (Will provide example)
I know I could move all the data into two columns, but that would make it Very long and the table is often looked at for reference. I would like to keep the table the way it is.
What I am looking for is that I can type the tank level(inches) into a cell and next to it it will return the tank level(gallons).
My current formula is
=INDEX('Calib. A & B'!$B$3:$B$47,MATCH(TANKS!$E$2,'Calib. A & B'!$A$3:$A$47,1))
Currently it compares cell E2 with A3:A47 and returns the corresponding value in B3:B47. It needs to search columns C, E, G, I, etc. Any ideas other than rearranging the spreadsheet?
There are different ways of obtaining the relevant rows/columns for the lookup:
=INDEX('Calib. A & B'!$A$3:$U$47,AGGREGATE(15,6,1/((TANKS!$E$2='Calib. A & B'!$A$3:$U$47))*ROW('Calib. A & B'!$A$3:$U$47)-2,1),AGGREGATE(15,6,1/(TANKS!$E$2='Calib. A & B'!$A$3:$U$47)*COLUMN('Calib. A & B'!$A$3:$U$47)+1,1))
The -2 for the rows argument of the index function is to adjust for the header position.
The +1 for the columns argument is to return the value one column to the right of the cell that matched.
This assumes, of course, that the values matching the lookup_value in E2 are only found in the "odd" columns of the data range.
As suggested by #TerryW, if your measure in E2 is not an exact match to the value in the data table (and the data table measurements are exact to the 1/8), you can roundup E2 to the next 1/8th.
Replace TANKS!$E$2 with ROUNDUP(TANKS!$E$2*8,0)/8
One way is with a long formula basically doing a union of results of the match on each column but having result as empty string when do not match it.
So we do a match against column A, if it doesn't find it it returns a blank string, if it finds it returns the number , then does the same for column C and concatenates the results and uses this on the index.
BUT this will only work if you search for an exact match.
For example:
=INDEX('Calib. A & B'!$B$3:$B$47,IF(ISNA(MATCH(TANKS!$E$2,'Calib. A & B'!$A$3:$A$47,0)),"",MATCH(TANKS!$E$2,'Calib. A & B'!$A$3:$A$47))&IF(ISNA(MATCH(MATCH(TANKS!$E$2,'Calib. A & B'!$C$3:$C$47,0)),"",MATCH(MATCH(TANKS!$E$2,'Calib. A & B'!$C$3:$C$47)))
You would need to add one more section for each column.

Excel Formula with IF... ELSE

Hi all,
I have this excel where by I need to find the location of the item if they are found in column B.
So In my F column, I tried to write ifelse formula which didnt work.which is
=IF(D2="NULL","NONE",C((D2))).
My idea is if D2 is not null, use the value in D column to find the location in C column. In this example, fish no 4, so it is found, my F column should show the value "C" using the value shown in D column and use it as Row no in C column
I hope you guys get the idea and help me out a newbie in excel. Thanks in advance
=vlookup($D2,$A$2:$C$6,3,0)
you can use that in column F. Place that formula in F2 and copy down.
you could technically use it in column E as well, but you would need to change the 3 to a 2.
you did not say what you wanted to do if the D value was "Null" so I am going to take a stab at the dark and wrap you lookup formula in an if statement that will deal with "Null" or empty cells
=IF(OR($D2="NULL",$D2=""),"",VLOOKUP($D2,$A$2:$C$6,3,0))
That is the alternative formula to place in F2 and copy down.
Use the formula:
=IF(D2<>"NULL",VLOOKUP(D2,A2:C6,3,FALSE),"Value is NULL")
Here is the working example:
Put formula in cell F2 and drag it down.
[edit]to pull proper location column, not just the row #[/edit]
Seems like a job for MATCH+OFFSET
Try this formula in cell F2:
=OFFSET($C$1, MATCH(E2,B:B,0)-1, 0, 1, 1)
Match is used to locate the value in the first argument (ie E2) within the range specified in 2nd argument (ie B:B). I use B:B but you could also use range B2:B30 or whatever more specific range you want. (I prefer the more generic B:B, though :) )
Third paramter "0" just indicates "Exact match".
This function will retun "#N/A" if nothing found.
OFFSET takes the result from MATCH to pick out the Location you want. The first parameter in OFFSET is the rows below (or above if negative) from the base row (in this case $C$1). the next is the column: 0 since we're in the column we want to be in. The last two are the size of the range: 1,1 is a 1x1 cell, so just 1 cell. If we did ...,2,3), that would be 2 rows high and 3 columns wide - or a 6 cell range. We're just after 1 cell here.
I've always preferred MATCH + OFFSET to other options, I just found they held up more robustly to changes in a sheet (ie new rows/columns added). So it's mostly personaly preference over VLOOKUP and INDEX. I honestly have never compared their actual performance, however, I've never had any issues with MATCH+OFFSET running slowly :)

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
screenshot here. (wont let me post i have no reputation)
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.

Matching two columns in one sheet to two columns in another

I need to assign a status to a row based on a VLOOKUP query between two worksheets. The problem is that the identifier is not always unique. However, the identifier + a date value should be unique. I wanted to use:
=VLOOKUP(A3&H3,'OtherSheet'!D:E,1,FALSE)
with A3 being the identifier and H3 being the corresponding date. D in the other sheet is the identifier and E is the date column. However, I keep getting #N/A.
Does this mean that there are no matches with the "identifier+date" or is Excel looking for "identifier+date" in either column D or E? If the latter is true, how can I let Excel concatenate D and E when matching to the search pattern?
There's work around without using CTRL+Shift+Enter.
Use this formula that will match A3 in D column of othersheet and H3 with the date in column E of the othersheet.
=INDEX(OtherSheet!F:F,MATCH(1,INDEX((OtherSheet!D:D=A3)*(OtherSheet!E:E=H3),),0))
The formula will return data from F column of OtherSheet.
You can modify the range OtherSheet!F:F as appropriate.
That formula is looking to find A3 concatenated with H3 (identifier&date) in OtherSheet ColumnD that contains only identifiers, so will inevitably fail. Yes, Excel is looking for “identifier+date” in column D.
Excel will happily concatenate A3 with H3 ‘on the fly’ (within a formula) but will not so happily concatenate OtherSheet ColumnD and ColumnE values in the same way. The conventional solution, because usually simplest in a case like this, is to prepare for the VLOOKUP by adding a helper column that concatenates the D and E values while preserving these in the same row as the value sought.
Because VLOOKUP will only look to the right this is usually a column that is added to the left of the value being searched for, so say either in C or by insertion of a column immediately to the right of C. However, since you are only checking a single column the location is not critical. You might add this (in OtherSheet) as ColumnZ, with a formula such as:
=D2&E2
copied down to suit*. Again because you are only checking a single column it does not matter which row such a formula is placed in.
However, because only checking whether A3&H3 exists in OtherSheet a simple alternative may be to apply COUNTIFS:
=COUNTIFS(OtherSheet!D:D,A3,OtherSheet!E:E,H3)
Any result other than 0 from this should indicate that the combination being tested for exists in OtherSheet – without need for a helper column.
* Depending on the format of your identifiers it is possible that concatenation may introduce ambiguity. For example ID90 concatenated with 11/1/15 may not be distinguishable from ID901 concatenated with 1/1/15, so it may be advisable if taking this approach to introduce a delimiter, in both the VLOOKUP formula (say A3&"|"&H3 rather than just A3&H3) and therefore also in the helper column, say =D2&"|"&E2.
You likely would want to use Index/Match instead. Vlookup is tricky when it comes to searches for multiple things. Here's the way you would use Index/Match:
Without knowing how your spreadsheet is set up, here's how you could do it:
If I understand correctly, you want to use A3 to find the match in OtherSheet!D, and H3's match in OtherSheet!E. Index match is perfect for this. Instead of vLookup, use
=Index(OtherSheet!D:D&","&Text(OtherSheet!E:E,"mm-dd-yyyy"),Match(A3&H3,OtherSheet!D&OtherSheet!E,0)), and enter with CTRL+SHIFT+ENTER.
What the Index() will return is the concatenated Identifier and Date, separated with a comma. If, though, you have a table like this:
That index/match formula will return "Batman". The index to return is the named range G2:G5. You're looking for a match on A1 (the Identifier) and B1 (the Date), then you're searching for (in the order you just put) the Identifier to be in the range E2:E5, and the Date to be in F2:F5. When there's a match for both, it returns the name in G2:G5.
Here's a link to a site on using Index/Match, and another and its advantages over vlookup.
