How do I auto-insert parethesis around prepopulated data in a worksheet? I
have a column of information that only if there is information, then I would
like it to be in parenthesis. For example,

A1: data
B1: data
C1: no data
D1: no data
E1: data

I would like to auto-insert parenthesis around the cells that show "data"
but to ignore cells that have "no data". This would involve only 1 column in
the excel file. The cells that contain data would look like this, example:
(Smith) or (Jones) rather than Smith or Jones.
