apply indirect arrayformula to the entire column in gsheet

Question

I get address of non-null cells from the formula below.

=arrayformula(if(A2:A="","",ArrayFormula(address(1,(mmult(isnumber(find("",A2:O99999))*1,sign(row(1:15))))))))

And I want values at the address I get from the formula. What should I add to the formula to get those values?

I want to insert the formula to "laststatus"

id	laststatus	...	statusA	statusB	statusC
A	statusC	...	done	done	done
B	statusA	...	done
C	statusB	...	done	done
D	statusC	...	done	done	done

Thanks.

Answer 1

You can use this formula:

=ARRAYFORMULA(REGEXEXTRACT(TRANSPOSE(QUERY(TRANSPOSE("|"&IF(C2:E5="done",$C$1:$E$1, "")),,COLUMNS(C2:E5))),"([^|]*)[|\s]*$"))

Output:

Answer 2

use:

=INDEX(REGEXEXTRACT(FLATTEN(QUERY(TRANSPOSE("×"&
 IF(D2:F="done", D1:F1, )),,9^9)),"([^×]*)[×\s]*$"))
