I have these 2 tables:
On column B i'm trying to get one of the Header Names of a feature that is not empty on Table B. I want it to be selected randomly. The order of the items in Table A can be different than the order of the items in Table B, I'll need some sort of INDEX MATCH here too.
Excel Version: Office 365
Attempted Formula: I tried to base my formula on this:
=INDEX(datarange,RANDBETWEEN(1,COLUMNS(datarange)),1)
but there are more things to consider, like header name if the index match of the same fruit isn't empty, so I know it is more complex.
Any help will be greatly appreciated.
Assuming you have Excel 365 and a volatile result is acceptable:
=LET(
Fruits, Table_B[Fruit],
Properties, Table_B[[Red]:[Green]],
PropertiesHeaders, Table_B[[#Headers],[Red]:[Green]],
ThisFruit, [#Fruits],
ThisProperties, FILTER(Properties, Fruits = ThisFruit),
ThisPropertiesFiltered, FILTER(PropertiesHeaders, ThisProperties <> 0),
ThisPropertiesCount, COUNTA(ThisPropertiesFiltered),
IndexRand, RANDBETWEEN(1,ThisPropertiesCount),
IFERROR(INDEX(ThisPropertiesFiltered,IndexRand),"-")
)
ThisProperties is the row in Table_B for your fruit. I left out the column for the fruit names.
ThisPropertiesFiltered is the names of the properties that the fruit has. I filtered the header names based on if the fruit row had a non-zero value or not.
IndexRand gets a random number between 1 and the number of available properties. Note, if there are zero available properties, ThisPropertiesFiltered returns #CALC! so ThisPropertiesCount will return 1. This is handled later on.
Last we use INDEX to get the random property name. IFERROR returns "-" if no properties were available.
Here are the tables:
Table_A:
Fruits
Result
Watermelon
Heavy
Melon
Green
Banana
Tropic
Peach
Red
Apple
Green
Table_B:
Fruit
Red
Yellow
Tropic
Heavy
Green
Apple
x
x
Banana
x
x
Peach
x
Melon
x
Watermelon
x

Since you have access to dynamic arrays you could try:
Formula in B2:
=LET(X,FILTER(E$1:I$1,INDEX(E$2:I$6,MATCH(A2,D$2:D$6,0),0)<>"","No Feature"),INDEX(X,RANDBETWEEN(1,COUNTA(X))))
Or without LET():
=#SORT(SORT(CHOOSE({1;2;3},E$1:I$1,FILTER(E$2:I$6,D$2:D$6=A2),RANDARRAY(1,5)),3,1,1),2,-1,1)
If you are working through actual tables this should spill down results under Random Feature automatically. However, if one does not use tables, you could nest the above in BYROW() if you are an 365-insider:
=BYROW(A2:A6,LAMBDA(r,LET(X,FILTER(E$1:I$1,INDEX(E$2:I$6,MATCH(r,D$2:D$6,0),0)<>"","No Feature"),INDEX(X,RANDBETWEEN(1,COUNTA(X))))))
This would not work with the 2nd option where we used '#' to parse only the topleft value of our array (implicit intersection).
The idea is that:
A combination of INDEX() & MATCH() will 'slice' the row of interest out of the lookup-table based on our input.
In the 2nd step we'd use FILTER() to only leave those headers where the elements from the herefor returned array are not empty. In the case all elements are empty, this function will return the value "No Feature" as a headsup for the users.
In our final step we combine INDEX() with RANDBETWEEN(). The latter will return a random integer between a LBound (1 in our case) and an Ubound which we based on the amount of returned elements.
I tried to visualize this below.
This question relates to the Schematiq add-in for Microsoft Excel.
Using =tbl.Lookup(table, columnsToSearch, valuesToFind, resultColumn, [defaultValue]) the values in the valuesToFind column have a consistent 3 characters to the left and then varying characters after (e.g. 908-123456 or 908-321654 - i.e. 908 is always consistent)
How can I tell the function to lookup the value based on the first 3 characters only? The expected answer should be the sum of the results of the above, i.e. 500 + 300 = 800
tbl.Lookup() works by looking for an exact match - this helps ensure it's fast but in this case it means you need an extra step to calculate a column of lookup values, something like this:
A2: =tbl.CalculateColumn(A1, "code", "x => LEFT(x, 3)", "startOfCode")
This will give you a new column that you can use for the columnsToSearch argument, however tbl.Lookup() also looks for just one match - it doesn't know how to combine values together if there is more than one matching row in the table, so I think you also need one more step to group your table by the first 3 chars of the code, like this:
A3: =tbl.Group(A2, "startOfCode", "amount")
Because tbl.Group() adds values together by default, this will give you a table with a row for each distinct value of startOfCode and the subtotal of amount for each of those values. Finally, you can do the lookup exactly as you requested, which for your input table will return 800:
A4: =tbl.Lookup(A3, "startOfCode", "908", "amount")
Working with 2 separate data sets (with duplicates)
Dataset is unique identified by an ID.
There may not be an entry for the timestamp I require.
Datasets are quite large, and due to duplicates, can't use vlookup.
Samples:
Table 1:
Device Name|Time Bracket| On/Off?
ID1 |06:20:00 |
ID2 |06:20:00 |
ID3 |06:30:00 |
Table 2:
Device Name |Timestamp |On/Off?
ID1 |06:20:00 |On
ID2 |06:50:00 |Off
ID3 |07:20:00 |Off
What I want to achieve:
I want an if statement to check if:
1) device ID matches AND
2) timestamp matches
If so, return the value of On/Off from Table 2.
If not, then I want it to return the value of the cell above it IF it's the same device, otherwise just put "absent" into the cell.
I thought I could do this with some IF statements like so:
=if(HOUR([#[Time Bracket]]) = HOUR(Table13[#[Timestamp Rounded (GMT)]]) and
minute([#[Time Bracket]]) = minute(Table13[#[Timestamp Rounded (GMT)]]) and
[#[Device Name]]=Table13[#[Device Name]], Table13[#[On/Off?]],
IF([#[Device Name]]=Table13[#[Device Name]], INDIRECT("B" and Rows()-1), "absent"))
(I put some newlines in there for readability)
However, this doesn't seem to resolve at all... what am I doing wrong?
Is this even the correct way of achieving this?
I've also tried something similar with a VLookUp, but that failed horribly.
Thanks all!
To not deal with array formulas or merging strings which, (not in your case) can still be wrong at the end, I suggest the use of COUNTIFS due to the fact, you have a very small amount of outcomes (just on or off)...
for the first table (starting at A1, so the formula is at C2):
=IFERROR(CHOOSE(
OR(COUNTIFS(Table13[Device Name],[#[Device Name]],Table13[Timestamp],[#[Time Bracket]],Table13[On/Off?],"On"))+
OR(COUNTIFS(Table13[Device Name],[#[Device Name]],Table13[Timestamp],[#[Time Bracket]],Table13[On/Off?],"Off"))*2
,"On","Off","Error"),IF(A1=[#[Device Name]],C1,"Absent"))
this will also show "Error" of a match for "On" and "Off" is shown... to skip that and increase the speed, you also could use:
=IF(COUNTIFS(Table13[Device Name],[#[Device Name]],Table13[Timestamp],[#[Time Bracket]],Table13[On/Off?],"On"),"On",
IF(COUNTIFS(Table13[Device Name],[#[Device Name]],Table13[Timestamp],[#[Time Bracket]],Table13[On/Off?],"Off"),"Off",
IF(A1=[#[Device Name]],C1,"Absent")))
For both the "Device Name" is at column A, "Time Bracket" at column B and "On/Off?" at column C while the table starts at row 1... If that is not the case for you, then change A1 and C1 so they match
(Also inserted line-breaks for better reading)
Picture to show the layout:
I picked the second formula to show how it works... also, this formula should not be able to return 0's... I'm confused
Couple of good suggestions, however using the helper column as suggested in the topic by Scott Craner above worked.
Created a helper column of concat'd device ID and timestamp for both tables, then did a simple VlookUp.
Another lesson learned: Think outside of the box, and go with simple solutions, rather than try + be too clever like I was doing... :)
I've seen several forum posts with the answer to this question, but I can't really understand how it's supposed to work, so I figured I'd come here for an explanation.
I have three columns:
CITY........|.Attribute 1.|.Attribute 2.|
Chicago..|........1........|........1........|
Chicago..|........1........|..................|
Boston....|........1........|........1........|
Chicago..|..................|..................|
Boston....|..................|..................|
Boston....|..................|........1........|
Chicago..|........1........|........1........|
Chicago..|........1........|........1........|
I want to get a count of the number of times a city has a "1" in Attribute 1 and Attribute 2. Normally, you would use COUNTIFS (=COUNTIFS(B2:B9,"1",C2:C9,"1"))which would give you the value of 4 - Rows 2, 4, 8, and 9.
But I want to be able to filter this list on the fly, and only be able to see data for Chicago rows, for instance. And thus, want to see the value of 3 - Rows 2, 8, and 9. But when the data is filtered, I still get the value of 4.
What code do I need to insert into my cell to get the value of 3 after filtering my list to only show Chicago, if I want to see when a city has a "1" in both Attribute 1 and Attribute 2?
Thanks!
Would this not work for Chicago?:
=COUNTIFS(A2:A9, "Chicago", B2:B9,"1", C2:C9, "1")
This would not require you to filter the data.
A variant of this could be used:
SUMPRODUCT((Attribute 1.=Satisfactory)*(SUBTOTAL(103,OFFSET(AW3,ROW(tblStudentProgress[D3 Activity])-MIN(ROW(tblStudentProgress[D3 Activity])),0))))
You could also create a helper column and sum attributes 1 and 2. If your helper column row equals 2 then you know both attributes exist. You could take this one step further and use concatenate to combine "Chicago" and your sum. And then filter by Chicago2.
I need to be able to search my whole table for a row that matches multiple criteria. We use a program that outputs data in the form of a .csv file. It has rows that separate sets of data, each of these headers don't have any columns that are unique in of them self but if i searched the table for multiple values i should be able to pinpoint each header row. I know i can use Application.WorksheetFunction.Match to return a row on a single criteria but i need to search on two three or four criteria.
In pseudo-code it would be something like this:
Return row number were column A = bill & column B = Woods & column C = some other data
We need to work with arrays:
There are 2 kinds of arrays:
numeric {1,0,1,1,1,0,0,1}
boolean {TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,FALSE,TRUE}
to convert between them we can use:
MATCH function
MATCH(1,{1,0,1,1,1,0,0,1},0) -> will result {TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,FALSE,TRUE}
simple multiplication
{TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,FALSE,TRUE}*{TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,FALSE,TRUE} -> will result {1,0,1,1,1,0,0,1}
you can can check an array in the match function, entering it like in the picture below, be warned that MATCH function WILL TREAT AN ARRAY AS AN "OR" FUNCTION (one match will result in true
ie:
MATCH(1,{1,0,1,1,1,0,0,1},0)=TRUE
, YOU MUST CTR+SHIFT+ENTER !!! FOR IT TO GIVE AN ARRAY BACK!!!
in the example below i show that i want to sum the hours of all the employees except the admin per case
we have 2 options, the long simple way, the complicated fast way:
long simple way
D2=SUMPRODUCT(C2:C9,(A2=A2:A9)*("admin"<>B2:B9)) <<- SUMPRODUCT makes a multiplication
basically A1={2,3,11,3,2,4,5,6}*{0,1,1,0,0,0,0,0} (IT MUST BE A NUMERIC ARRAY TO THE RIGHT IN SUMPRODUCT!!!)
ie: A1=2*0+3*1+11*1+3*0+2*0+4*0+5*0+6*0
this causes a problem because if you drag the cell to autocomplete the rest of the cells, it will edit the lower and higher values of
ie: D9=SUMPRODUCT(C9:C16,(A9=A9:A16)*("admin"<>B9:B16)), which is out of bounds
same as the above if you have a table and want to view the results in a diferent order
the fast complicated way
D3=SUMPRODUCT(INDIRECT("c2:c9"),(A3=INDIRECT("a2:a9"))*("admin"<>INDIRECT("b2:b9")))
it's the same, except that INDIRECT was used on the cells that we want not be modified when autocompleting or table reorderings
be warned that INDIRECT sometimes give VOLATILE ERROR,i recommend not using it on a single cell or using it only once in an array
f* c* i cant post pictures :(
table is:
case emplyee hours totalHoursPerCaseWithoutAdmin
1 admin 2 14
1 him 3 14
1 her 11 14
2 him 3 5
2 her 2 5
3 you 4 10
3 admin 5 10
3 her 6 10
and for the functions to check the arrays, open the insert function button (it looks like and fx) then doubleclick MATCH and then if you enter inside the Lookup_array a value like
A2=A2:A9 for our example it will give {TRUE,TRUE,TRUE,FALSE,FALSE,FALSE,FALSE,FALSE} that is because only the first 3 lines are from case=1
Something like this?
Assuming that you data in in A1:C20
I am looking for "Bill" in A, "Woods" in B and "some other data" in C
Change as applicable
=IF(INDEX(A1:A20,MATCH("Bill",A1:A20,0),1)="Bill",IF(INDEX(B1:B20,MATCH("Woods",B1:B20,0),1)="Woods",IF(INDEX(C1:C20,MATCH("some other data",C1:C20,0),1)="some other data",MATCH("Bill",A1:A20,0),"Not Found")))
SNAPSHOT
I would use this array* formula (for three criteria):
=MATCH(1,((Range1=Criterion1)*(Range2=Criterion2)*(Range3=Criterion3)),0)
*commit with Ctrl+Shift+Enter
