I would like to restore some important functionality in Excel 2007 which has become disabled for a spreadsheet which I saved
in different file formats.
I opened an Excel 2003 file with Excel 2007 and used 'Save As' into different formats
(default, macro-enabled, binary) to see the resulting file size.
A number of Ribbon items are now greyed out
for this file, including,
- Insert - Tables, Illustrations, charts, etc.
- Styles - conditional formatting and Format as table,
- Formula Auditing
- Data - just about all of them
- View - some of the Window items.
Also, I cannot resize or move a button on a worksheet.
Attempts to 'Save As' into the Excel 2003 format cause
Excel 2007 to hang.
What caused so many features to become disabled?
How do I restore them?
Thanks in advance for any suggestions.
