Help recovering a file....

You're screwed unless you have a backup. In the future, if you make a duplicate of a file you want to backup, change the file extension to .bak instead of the file type your using.

So, if you have a file named techboard.xlsx, make a copy in a backup folder or same working folder and name it techboard.bak, then if you need to use it just change the file extension back. This way, you never have to worry about opening the backup file by double clicking it in the file manager.

Thanks.

As soon as I hit the save icon I knew I was screwed was just hoping for something easy. I typically do a save as any time I open a file to use as a base for a new file but didn't do it this time as I was in a hurry. I have a pdf of the original so I can recreate the original, just will take time I was trying to save.

It's been many years since I used Excel, so these other guys may have a better suggestion. You could always search "restore previous file" (or version) or something similar in the Excel help section or on the Microsoft website.
