I have been trying to open a file in Excel, that was CREATED in Excel and it keeps telling me that the file format is not valid. What happened? How can I fix it?
I did open the file before in Word. Could I have screwed it up by opening it in word? Because now it will not open in Excel, and I really need it to.
There were 2 spreadsheets and I jsut opened the 2nd sheet in Word, and I need the first one. What can I do? Have I lost that file for good?
Thank you.
