Hello friends. I'm using MS Office 2007 with Windows 7. Everything was fine except last morning. This Sunday I made some files with file extension .xlsx for my official work in MS Excel. But on the next day when I presented them to my boss she couldn't open them. She completely went off on me. Now I have no more time, I said no more time. I know my files have been corrupted, but really don't know why? I'm searching a quick but effective method to fix my this problem. Is there anyone who can help me?
I'll surely appreciate you if you do help me or you don't.
