Microsoft Excel

I opened an Excel 2003 file on one specific company computer and the file’s columns show up as condensed. The columns are so condensed that I can see columns ABC…thru…CC on one sheet. Because the columns are so condensed, the file is unreadable. I checked the column width and it reads 7 but the columns continue to show up condensed and unreadable.
When I open the same Excel 2003 file on any other company PC, the columns come out perfectly fine and readable. All company PCs run Office 2003. What is the problem with the specific company computer?
