Forum Thread: excel data store

Dude, in case nothing helps you, I mean guide or tutorials, articles and so on, then I would advise repair excel file

This one forum is about MS Excel, read this theme, probably you'll find something helpful - http://www.excelforum.com/excel-general/1079312-excel-corrupt-file.html

Techrepublic article is also can give you ways for resolving: https://www.techrepublic.com/blog/10-things/10-ways-to-recover-a-corrupted-excel-workbook/

Alternatively apply steps below...

1. Rename the file and remove the .xlsx or .xls extention etc e.g. if my file is called test.xlsx I remove the '.xlsx' - you will get a warning message saying this could make the document unstable - accept it
2. The document icon should now have turned white (the document won't look like an excel document anymore)
3. Open a blank excel document by hitting start -> all programs -> Microsoft office -> excel (this may be different if you're not on windows 7)
4. In your blank excel document hit file -> open
5. Navigate to the document you renamed above and select it, now click open
6. It should now open the document
