Hi LMR! The solution posted by MartinW will work for you. Couple of points
you might want to consider.
1) If you need a space after the ")", then use ") " (there's a space
included) rather than the ")".
2) Assuming your original data is in Col. A and you've put the formula
proposed by MartinW in col. B, once you have the formatted data in col. B, do
this. Click on top of col. B (the "B" itself). That selects the entire
column. Then copy the entire column to the clipboard (Ctrl-C). Then select
another empty col, eg. col C. Click in cell C1 and then do a Paste Special,
selecting Values. That'll copy all the values in col B into col C, WITHOUT
copying the formula in col. B. After you've done this, you can choose to
delete col A (the one with the old format) and col B (since that's dependent
upon the existence of data in col A).
Feel free to ask if something isn't clear.
