Hi Ruslan (Rus) Akhmadiev,
Thanks for your post in Microsoft Community.
Based on your description, it seems like that you wish to revert the view of your Excel app to a previous version, we can fully understand your distress and will do everything we can to help you.
- Could you please specify which version of Excel you are currently using? You can find this information by opening an Excel worksheet, clicking on 'File', then 'Account', where your Excel product details should be displayed in the middle of the screen.
- Are you referring to the classic view of Excel like this?
If that's the case, you may need to rollback to an earlier version to regain that view, as the modern Office design started rolling out from 2021 onwards. You can refer to this link: Update history for Microsoft 365 Apps for instructions on how to revert your Office installation to a version prior to v2108.
Please share the outcome of these troubleshooting steps with us. We look forward to your update. If you have further questions, please feel free to contact us!
Thanks for your cooperation and understanding. I hope that you are keeping safe and well!
Best Regards,
Thomas C - MSFT | Microsoft Community Support Specialist
