File opening issue (concerning betas)

Hudzy · 24 Nov 2009 at 17:03

I just found some old excel documents I'd been working on a few years ago that don't open. I get this message:

'untitled.xlsx' cannot be opened because it was last saved using a Beta version of Excel that is no longer supported. To open the file, first use a supported version of Excel to save the file, and then try again.

Now I'm pretty sure it's refering to the Office 2007 Beta I was using for a bit since that's the only beta I recall using. I'm not terribly fussed about these old documents, but is this likely to happen to files created in the 2010 Beta once I start using the release version?

Don't know about your question re: Office 2010 but does Google docs or OpenOffice open them?

The XML format for Office 2007 was one of the new features. Perhaps the reason why the full version can't open them is due to a change in the format between BETA and release.

I opened a Word document created in Word 2010 with Word 2007 just fine yesterday.

I probably should have tested OpenOffice etc. but I really didn't care enough about the files.

2010 file compatability with 2007 sounds promising anyway. Again, it's nothing important else I wouldn't be using the beta.

I honestly can't see Microsoft breaking the file formats for 2010. You can never guarantee what version of Office someone will be using when you send them a document [or you receive a document]. Having two different versions of docx, xlsx etc would be a royal pain in the buttock region.
