How do I merge two Excel columns into one?

Solution 1:

This is the simplest way I would do that with just a formula.... if the values are in columns A and B, then this formula in C1, then copied down as far as you want, it will show blanks when the values run out:

=IF(ROW()<=COUNTA(A:A), INDEX(A:A,ROW()), IF(ROW()>COUNTA(A:B), "", INDEX(B:B,ROW()-COUNTA(A:A))))
