A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hi,
Thanks for reaching out to the Microsoft community and for explaining the issue. What you’re experiencing, Excel sheets appearing upside down or mirrored on a Mac, with the first row showing as number 36, is a known glitch that can occur after transferring data or updating macOS and Office.
This usually happens because of outdated or mismatched versions of macOS and Microsoft Office, a corrupted installation, or sometimes just a display glitch caused by an accidental setting.
The best way to fix it is to make sure both macOS and Office are fully updated, as this often resolves the problem right away. Restarting your Mac can also help clear temporary display issues. It’s worth checking Excel’s view settings to confirm nothing unusual is enabled. If the issue persists, repairing or reinstalling Office might be necessary. As a quick workaround, scrolling down and back up can temporarily correct the view, but it’s not a permanent solution.
If updates don’t solve it, the problem may be due to compatibility between older Office versions and newer macOS releases. Upgrading to the latest Office for Mac usually fixes it completely.
Hope this helps! Let me know how it goes.
Kind regards,
Edward
