Ah well, you've probably gone home from work. Assuming your names do start in A1 and you want them in C1 across to E1 and then down, you can put this formula in C1:

=INDEX($A:$A,(MOD((COLUMNS($C:C)-1),3)+1)+INT((ROWS($1:1)-1))*3)

Copy into D1 and E1, and then copy C1:E1 down as far as you need to.

Hope this helps.
