Can't open Excel

Question

Just installed Office 2024 and Excel will not open.

Answer 1

Follow these steps on macOS to fix Excel not opening after installing Office 2024:

1. Quit all Office apps

• If any Office apps are partially open or stuck, force quit them from the Apple menu → Force Quit.

2. Completely remove the Office apps and data

• Open Finder → Applications.
• Use Command + click to select all Microsoft 365/Office apps (Word, Excel, PowerPoint, Outlook, OneNote).
• Ctrl+click the selected apps and choose Move to Trash.
• In Finder, on the menu bar select Go → Go to Folder… and enter:
  • ~/Library/Containers/
• In that folder, delete the following (if present):
  • com.microsoft.Word
  • com.microsoft.Excel
  • com.microsoft.Powerpoint
  • com.microsoft.Outlook
  • com.microsoft.OneNote
• Go back to ~/Library and open Group Containers.
• Move these (if present) to Trash:
  • UBF8T346G9.ms
  • UBF8T346G9.Office

3. Reinstall Office 2024

• Open a browser and sign in to the Microsoft account that owns Office 2024 at the services page: https://account.microsoft.com/services (from the context).
• Download and reinstall the Office apps for Mac from there.
• After installation, start Excel first and confirm it opens before trying the other apps.

If Excel still will not open or crashes after these steps, use the same account page to verify the subscription/license status and install any available updates for Office for Mac.
