See if one of these works for you:

Note: Commit these array formulas by holding down [Ctrl] and [Shift] when
you press [Enter]

1. The address of the first empty cell in Col_A:
=CELL("address",INDEX(A1:A65535,MATCH(TRUE,ISBLANK (A1:A65535),0)))

2. A reference to the first empty cell in Col_A:
=INDEX(A1:A65535,MATCH(TRUE,ISBLANK(A1:A65535),0))

3. The row number of the first empty cell in Col_A:
=MATCH(TRUE,ISBLANK(A1:A65535),0)

Does that help?
