MSWord allows you to open .xls files. The bad news is that if you save that
file in MSWord (as an MSWord document with .xls as the extension), that you've
lost most of your excel features--formulas and the like.

Do you have a backup copy of this workbook?

Any chance you emailed it to someone--you could have an earlier version in your
sent folder--or ask the recipient to send a copy back.

(or maybe your IT folks back up the files??????)

(I think you did the best you could (open in MSWord and copy|paste into Excel),
if you don't have a backup.)
