How to repair and recover corrupt MS excel file? I am unable to open corrupt MS Excel file due to virus infected, I have crucial Workbook sheet got lost. When you open a workbook that has been corrupted, Excel automatically starts File Recovery mode and attempts to reopen and simultaneously repair the workbook.
Excel Recovery File Extension
I am a Special Education teacher and created an excel file that contains important student info. I tried to open it this morning and received the following message: 'Excel cannot open the file ' filename.xlsx' because the file format for the file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.' I searched the net and found the Microsoft standard 'open and repair' option, but the file still comes up corrupt. Does anyone have any other tricks I might try? I am using Excel 2016.
