Excel Formatting not saving

[madhdhi]

I have an excel workbook that has a few work sheets.
Fomatting on this work book is basic - fonts, background color and very
basic formulas

For some reason the formatting has disappered from this spreadsheet and i
can not correct it
if i try to copy the data onto another work book, even then the formatting
does not retain when i reopen the file after saving... please help...

Are you certain the format of the saved workbook is Normal xls (or xlsx) as
opposed to wks or csv or dif, etc.
