Hi,

accidentaly my .xlsx file has been deleted (with shift button). i recovered my deleted file with pandora recovery, and it works.

but when i open my file, it show that "excel found unreadable content in .xlsx. do you want to recover the content of this workbook?"
then i click yes.

and it comes to "excel cannot open the file .xlsx because the file format or file extension is not valid."

is my file can be fix or its permanently corrupt?

please answer and give suggestion.
