If you accidently save a file in another format, is there any way.

[Jay]

I can't open an EXCEL file. I get an error message which says "the file is
in an unrecognizable format". The only thing I can think of is when I saved
it the last time, I didn't make sure it was saved in EXCEL. Maybe I saved it
in another format? If so, is there ANY way to retrieve the file?

To where did you save it and from where are you opening it?

Files saved directly to or opened from removable media can become corrupt.

Otherwise...........

Generally the case is that you have opened the file in Word and saved it.

If so, it is now a Word *.doc file

You can open with Word and perhaps recover some(most) data but no formulas,
formatting and other stuff.

The "other stuff" means I have never done this to myself so have no idea what
is gone or recoverable.
