Transpose Diagonal to row in Google Spreadsheet?

问题

I've tried to find a formula that would return the diagonal of an array A1:D4 as follows: A1 B2 C3 D4

I found this one, which returns a column, but I can't find out how to order the values in a row instead.

=INDEX(A1:D1,,ROWS($1:1))

(paste in the columns below)

A TRANSPOSE on the result would of course do the trick, but I'd appreciate something slightly more elegant. Thanks!

If you use the exact range you mentioned (A1:D4) then this should work

=ARRAYFORMULA(TRIM(QUERY(IF(ROW(A1:D4)=COLUMN(A1:D4), A1:D4,),,ROWS(A1:A4))))

(No need to fill down.)

If you want to get the diagonal values of any range (here: B11:E14), try

=ARRAYFORMULA(TRIM(QUERY(IF(ROW(B11:E14)-ROW(B11)+1=COLUMN(B11:E11)-COLUMN(B11)+1, B11:E14,),,ROWS(B11:B14))))

How about this, then as you pull it across it will go down the diagonal

=index($A$1:$D$4,columns($A1:A1),columns($A1:A1))

or the equivalent of your original formula would be

=index(A1:A4,COLUMNS($A1:A1))
