When I try to open spreadsheets created in Excel 2007 with Excel 2010, I get the error: "Excel found unreadable contenct in 'file name'. Do you want to recover the contents of this workbook? If you trust the source of this workbook, click Yes". Then a Repairs dialog box comes up saying: "Excel completed file level validation and repair. Some parts of this workbook may have been repaired or discarded. Removed Part: Print options." File then opens fine.
We receive Excel 2007 from various sources. One of my problem is that we are just starting to migrate people to Windows 7 and Office 2010, with most people still on Office XP. The file format converter for Excel 2002/2003 does not work with these Excel 2007 files. The other problem is that we have macros that are used to open Excel files and import data into other Excel files. Pretty hard to modify these macros to allow for some files that are going to pop up this error, and others that do not.
What is causing this problem, and what fix is available? We have asked that people save the Excel files in Excel 97-03 format before sending to us, with mixed results.
