.xlsx document

I use MS Excel 2016 almost every day. I have one big file more than 10mb. Today I cannot open it, the application showed an error - This file is not in a recognizable format. I applied excel recovery function, but it didn’t help. Is there any resolutions to open my file?

Ok, did you try to open excel document in another version of MS Excel? If you have the same issue, then you may try to use https://excel.recoverytoolbox.com/ Recovery Toolbox for Excel or apply a method below...


A corrupt excel spreadsheet can be repaired by using Open and Repair technique. It is a built-in repair function that opens a corrupt excel file forcefully. 
*Open MS Excel > press Ctrl+O > locate corrupt excel spreadsheet and select it.
*Click on the arrow shown beside Open button > select Open and Repair.
It will take just a few seconds to be completed and selected file will be opened, if possible.

Are you opening the excel document in JIRA or another Atlassian application? Otherwise this is a weird place for this question.

I tried via Atlassian, and moreover via MS Excel, but I can't

Try this, it will restore your version from yesterday



Thank you all for solutions.
