To resolve this issue, try the following methods, in order, until the issue is resolved.
Step 1: Quit all programs

Use the "Repair Disk Permissions" option
You can use the Repair Disk Permissions option to troubleshoot permissions problems in Mac OS X 10.2 or later versions. To use the Repair Disk Permissions option, follow these steps:
Note The Disk Utility program only repairs software that is installed by Apple. This utility also repairs folders, such as the Applications folder. However, this utility does not repair software that is in your home folder. For more information about the Repair Disk Permissions option, see the following AppleCare article: https://support.apple.com/en-us/HT201560
Open Excel and check if the issue is resolved. If it is not, continue to Method 3.
Create and use a new user account
To create a new user account, use the following procedure.
Note You many have to reinstall Office if you log on with a new account.
Open Excel and check if the issue is resolved. If you can save when you use a new user account, contact Apple support to troubleshoot your existing account. If you do not want to keep your existing account, you can rename the "Test" account that you create in the following procedure, and continue to use that account. If it is not, continue to Method 4.
