HOW TO FIX EXCEL NOT RESPONDING ON MY MAC

Hello, thank you for reaching out to Microsoft Q&A.

May I please know if the other Office 365 apps, like Word or PowerPoint, work normally?

If the issue is especially with the Excel program, you can try these methods.

1. Update Office apps - Open an Office app such as Word, then on the top menu, select Help > Check for Updates. If you don't have the check for updates option, run the Microsoft AutoUpdate tool and check for updates again. You can download the tool from the link below. https://go.microsoft.com/fwlink/?linkid=830196
2. Uninstall and re-install Excel - Open Finder > Applications.

Select the Excel program from the list and drag/move it to Trash.

Then, download the latest version of the Excel app from the link below.

3. Run Disk Utility Scan on your MAC - Go to finder > Applications > Utilities> Disk Utility.

You can select the disk and start the scan. Wait for the scan to complete.

This will scan your disk for errors and automatically repair them.

Let me know if you still need more help.
