Find First Cell Value
This is a way that I thought up (but I may not be the first)
In B1 enter =IF(A1="","",ROW()) and drag down
Then in C1 enter =INDEX(A:A,MIN(B:B))
or
For a range such as A1:A100, use this formula
{=INDEX(C1:C100,MATCH(TRUE,C1:C100<>"",0))}
Must be entered as an array. (Push Ctrl, Shift and Enter simultaneously)
