I have created a file in Excel 2007 with extension (.xlsx) and i have been
working on this file for several days. I don't face problems until yesterday
i tried to open the file, it prompts me with this error message:
"Excel cannot open the file '2007.xlsx' because the file format or file
extension is not valid".
Please advise how i can open this file. This is a very important file and i
need it urgently.
Thanks,
