When you say "formula" are you talking about the format itself?
If you select the rows then "Format-Cells-Special" and click the
Social Security Number format it will apply that format to all the
selected cells.

Why can you not use a copy and past special when using this function.
I have several hundred rows that need to be formatted, and it does not
allow me to copy the formula to multiple cells.
