A friend created an Excel spreadsheet at work and when trying to open it at home it wouldn't open. Comes up with "file format or filoe extension not valid. Verify that the file has not been corrupted..". Using Office Home & Student 2010 on two different computers with different OS's (XP, & Vista 64bit) with the same result. Xlsx files created at home and taken to work can be read on the same USB stick, but anything created at work comes up with the same error. Any ideas?
Thanks for the quick reply. I changed the file extension to .xls and a slightly different error came back...."File is in different format than specified by the file extension." So it seems that the file extension is correct at xlsx. I changed it back to .xlsx and it came back with the same error.
IF the files were created at work and can be read only at work there may be a digital certificate that the good people in IT installed on your work machines so that with out the digital certificate the files cannot be accessed.
