不是在Google表格中的ArrayFormula的IF语句中进行CONCATENATE

Question

Make Google Spreadsheet Formula Repeat Infinitely helped me to expand my formula indefinitely and other StackExchange results helped me get to here:

=ARRAYFORMULA(IF((AF2:AF="")," ","L"&ROW(F2:F)&":AD"&ROW(F2:F)))

However, when I tell "L"&ROW(F2:F)&":AD"&ROW(F2:F) to CONCATENATE, every row gives a results as if it was CONCATENATE(L2:AD2).

I tried =ARRAYFORMULA(IF((AF2:AF="")," ",CONCATENATE("L"&ROW(F2:F)&":AD"&ROW(F2:F)))) and =ARRAYFORMULA(IF((AF2:AF="")," ",CONCATENATE(INDIRECT("L"&ROW(F2:F)&":AD"&ROW(F2:F))))) but neither are working.

I am trying to get each row to CONCATENATE(L2:AD2) then CONCATENATE(L3:AD3) then L4:AD4 and so on.

Any help is most appreciated.

Answer 1

To make more easy to explain and understand by using an example, assume that the source values are in the range A2:C3

Instead of using

ARRAYFORMULA(CONCATENATE(A2:C3)) 

use

ARRAYFORMULA({A2:A3&B2:B3&C2:C3})
