Trying to nest a transpose formula inside an array formula

Here's the sheet: https://docs.google.com/spreadsheets/d/1TbPKehggzCGWy6LyEuzHZc5RouBHhyju35bqIGpInhM/edit#gid=14120435

I know how to transpose the data in colA (=Transpose(A2:A)). I know how to write an array formula to output the data i'd like (F1), but I'd like to nest the Transpose formula into the formula in F1 so that as items are added to colA, the table on the right populates with the header rows relying on the values in A2:A and the data as it is in ColF

Solution

  • You could try:

    =ARRAYFORMULA(LET(header,TOROW(A2:A,1),{header;IF(D2:D="",,E2:E*VLOOKUP(header,A:B,2,))}))

    Or:

    =ARRAYFORMULA(LET(header,TRANSPOSE(FILTER(A2:A,A2:A<>"")),{header;IF(D2:D="",,E2:E*VLOOKUP(header,A:B,2,))}))
