Clear the Microsoft Excel Cache on Mac

Deleting the corrupted cache folder often resolves global application glitches where the spacebar stops responding across all spreadsheets.

When Excel's preference or cache files become corrupted, it can cause unusual input behavior, such as ignoring spacebar key presses. Resetting the container folder forces Excel to rebuild these files freshly.

1
Close Excel

Ensure Microsoft Excel is completely closed. You can do this by right-clicking the Excel icon in the Dock and selecting Quit.

2
Access the Library folder

Open Finder on your Mac. Press the keyboard shortcut Command + Shift + G to open the 'Go to Folder' window.

3
Locate the Containers folder

Type '~/Library/Containers' into the search box and click Go to open the hidden Containers directory.

4
Move the Excel cache

Find the folder named 'Microsoft Excel', drag it out of the Containers folder, and drop it onto your desktop as a temporary backup.

5
Restart Excel

Reopen Excel and try typing a space in any cell. If the spacebar works, you can safely delete the folder you moved to the desktop.

Safe Process: Moving the cache folder will not delete your saved Excel workbooks. It only resets your temporary app preferences.

Frequently Asked Questions

Why does the spacebar work in Word but not in Excel on my Mac?

This usually indicates that the issue is not with your Mac's physical keyboard but rather an application-specific glitch or a corrupted Excel cache that only affects the spreadsheet program.

Will clearing the Excel cache delete my saved spreadsheets?

No. Moving the Microsoft Excel container folder to your desktop only resets temporary app preferences and cached files. Your actual workbooks stored on your computer or cloud remain perfectly safe.

What should I do if the spacebar only fails in one specific workbook?

If the issue is isolated to a single file, the workbook itself may be corrupted. Creating a brand-new blank workbook and pasting the original data into it typically resolves the problem.

How does Mac Safe Mode help fix Excel keyboard issues?

Booting your Mac in Safe Mode prevents certain background software and system extensions from loading. If the spacebar works perfectly in Safe Mode, a background app or utility is likely interfering with Excel's keyboard inputs.
