it depends on whether it is numeric formated with the dashes or Text with the
dashes embedded.
goto <format<cells<number and select general
if the dashes are still there it is text.
select the cells and use find replace (Find the dash replace with nothing)
the cells will still be text, so enter 1 in a cell copy it select the SSN
cells and paste special Multiply

I would like to convert a text social security number (###-##-####) to a

Any help is greatly appreciated.
