Windows 10: how to access a previous version of excel

I attempted to open current version and got a error message: .......file format or file extension is not valid .......; fil extension is valid showing .xlsx.Upon viewing version history the 2 most recent versions on file are dated 24-06-29. The latest shows 0KB data wiped some how. The next on the list is same date and time showing 36.0KB.How does one access a precious version of an excel file.

reverting to previous build/version

Hi,

Thank you for posting your query on Microsoft Community.

I would appreciate if you could answer few questions to narrow down the issue.

• When the computer did froze? Is it when you tried to roll back?
• Did you receive any error message?

I suggest you to remove all the external devices plugged in to the computer and check if it helps to resolve the issue. If the issue persists, please restart the computer and check whether it rolled back or not. If it loads Windows 10,
I suggest you to download the latest ISO of Windows 10 and perform automatic repair.

Steps to perform repair:

a) Insert the installation DVD or USB
and boot Windows 8 from it.

b) In the ‘Windows setup’ page select the language to install’, ‘Time and currency format’ and the ‘keyboard or input method’ and click on ‘next’.

c) Click on ‘Repair your computer’ and select ‘Troubleshoot’.

d) Click on ‘Advanced options’ and select ‘Automatic Repair’ and select the operating system.


If you really would like to rollback, I suggest you to refer the below article on How to go back to the previous operating system (Windows 7/8.1) from Windows 10.
