"Unreadable Content" Error

[Buffettology]

When I open files in excel 2007 I get this error every so often from files sent to me from co workers. I can't open them or sometimes when I can there are errors all over the file. They have excel 2007, 2010, and 2013. Error comes from any of these. No code or macros in the files. Any idea what this could be? Thank you so much in advance.

2007 excel may not be forward-compatable in all ways. If they use some feature that never existed in 2007, it won't work. There seems to be a compatability checker your coworkers can use.

But what about 2007 to 2007 errors?

I'm not sure what to say about those.

Explain the problem properly and write the error message in the quote. So it will be easy to solve your problem.

I sometimes can't open an excel 2007 file sent to me from someone else (I have excel 2007). The error message is in my title, Excel found "Unreadable Content".
