'Interleaf' columns of data

[Testing123]

I need to take two large columns of data and 'interleaf' them. So, if I
have data in columns A and B, I want in column C:

C1 = A1
C2 = B1
C3 = A2
C4 = B2
C5 = A3
C6 = B3
C7 = A4
C8 = B4

etc.

How can I do this?

Thanks.

In C1: =OFFSET($A$1,(ROW()-1)/2,1-MOD(ROW(),2))
Autofill that down through column C.

For a non-volatile option, you can try this:

In C1, or *any* cell in any other column besides A or B, enter:

=INDEX(A:A,(ROW(A1)+1)/2)

AND, in the cell right *under* the first cell, enter:

=INDEX(B:B,(ROW(A1)+1)/2)

Then, select *both* cells and drag down to copy as needed.
