Problem in libre office

I am facing problem in libre office. I have save the draft of libre excel file in my gmail from linux and when opening it in windows 7 or 8 or xp then it shows the file in corrupted format. It also shows the error- The file you are trying to open "example.xls" is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Has anyone arrived at this problem. Please help as whole of my data is lost. Any help would be appreciated. Cheers

have you tried changing the tag? document.xls etc or try opening in google docs.. perhaps you dont have windows office installed?

When i copy in the entire page form sites to libre office worksheet it does not copy properly. Anybody know i don't want to remove ubuntu to previous window 7.

When saving from one format and expecting to open in another application, you need to do a "save as" and choose a format to save that is a closer fit to the application you will be opening it in.
