You can change or Create or delete the Comma style. And I bet that's what
happened to the person sending you the file.

You can do it manually:

Format|Style (in xl2003 menus)
or
Home tab|Style group|Cell Styles icon (on the xl2007 ribbon)

Change or create the comma style to what you want.

Or......

Start a new workbook.
Open the offending workbook.

With the offending workbook active, click on Format|Style
Click on the Merge button
Select the new workbook
and click ok

Since styles live in workbooks, you'll have to do this to every workbook that
lost its style.
