We receive an unreadable content error in our Excel (happens on both
computers) spreadsheet. This was a 2003 file that we have converted to 2007
and has an extension of xlsm.

Excel stripped the entire workbook of all formats (it called it repair-which
is much better I'm sure than what used to happen in 2003 which was the file
would not open at all), but seems to have kept the formulas intact.

I've read alot of material here on the forums and think this stems from a
2003 issue - but I've not really found any real solutions. We are redoing
some of the formats on some of the tabs, but the worksheet is very
complicated and redoing the sheet from scratch is a shudderable option.

We certainly appreciate any assistance from this wonderful forum.
Thank you in advance.
