I hit Post too quickly. You can put this in a blank column next to your data
(adjusting the cell references as needed) and copy down. Then, copy the cells
with the Formula and do Edit | Pate Special | Values.
If the data matches what you want, delete the original column.

If VBA is an option for you, Bob Phillips's post should do the trick.
