Unfortunately those names indicate a corrupted workbook.
If you have a recent backup without those corrupt names I would go back
to it.

Otherwise you could try saving as HTML format and editing the HTML to
turn the corrupted names into alphabetic characters and then re-opening
and saving as XLS. Be sure to keep a backup copy; you will lose some
features in round-tripping to HTML, depending on which version of Excel
you have [it always helps if you tell us]
