Hi,Microsoft Mac user_672
Thank you for consulting the Microsoft community and reporting your issue.
We understand that you have recently experienced an issue with Excel shortcuts not working. This does affect your productivity, we understand the inconvenience and will do our best to assist you.
In order to further diagnose the issue, we need to confirm with you:
- Are these specific shortcuts the only ones that are not working, or are other shortcuts also experiencing this issue?
- Are the shortcuts in specific files not working, or are these shortcuts not working for all files? This helps us to troubleshoot whether it is a file issue or an application issue.
I see the version information on the test machine as shown below, so I suggest you can check again if there is a version that can be updated and try to update to the latest version to check.

In the meantime, try the following steps to troubleshoot the issue:
1-Check the System Preferences:
On Mac, sometimes the keyboard shortcut settings in System Preferences may affect the Excel shortcut function. You can go to System Preferences > Keyboard > Shortcuts to make sure there are no settings that conflict with Excel.
2-Restart the Excel application:
Sometimes simply closing and reopening Excel can restore the normal functionality of keyboard shortcuts.
3-Check Excel's language and regional settings:
Make sure that Excel's language settings are the same as the language you are used to operating in, and check that the regional settings are correct.
If the above methods fail to solve the problem, you can try the following further actions:
1) Reset Excel Preferences
Sometimes resetting Excel's preferences can fix strange behavior in the program.
- Go to the desktop, mouse click down to the desktop, click go to at the top of the screen hold down the option key and select Resource Library (this is the hidden folder, only hold down the option key on the keyboard will be shown in go to)
- Go to the Containers folder and delete the following files com.microsoft.excel
2) Reinstall the Excel application
If the problem persists, try uninstalling and reinstalling the Excel application to see the problem. Click here for the detailed steps.
Please note that before performing a reset or deletion, it is recommended that you back up your files to prevent accidental loss.
We understand the importance of shortcuts for productivity and appreciate your patience and understanding. We look forward to helping you solve your problem as soon as possible.
We look forward to your updates.
Best wishes.
