Fix Excel Spacebar Not Working in Cells on Mac
Question details
The user is unable to type spaces using the spacebar within Excel cells on a Mac.

- Product
- Microsoft Excel for Mac
- Device & OS
- macOS
- Scenario
- Entering or editing text data within an Excel spreadsheet cell.
- Observed behavior
- Pressing the spacebar does not insert a space character between words inside the cell.
Before troubleshooting, check if the spacebar works normally in other applications like Word or Safari to rule out a hardware issue with your Mac keyboard.
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.
Ensure Microsoft Excel is completely closed. You can do this by right-clicking the Excel icon in the Dock and selecting Quit.
Open Finder on your Mac. Press the keyboard shortcut Command + Shift + G to open the 'Go to Folder' window.
Type '~/Library/Containers' into the search box and click Go to open the hidden Containers directory.
Find the folder named 'Microsoft Excel', drag it out of the Containers folder, and drop it onto your desktop as a temporary backup.
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.
Migrate Data to a New Workbook
Use this method if the spacebar issue only occurs in one specific Excel file, which strongly indicates the file itself is corrupted.
Reinstall Excel and Boot in Safe Mode
If clearing the cache fails, the app installation may be corrupted or a background app might be interfering with your keyboard.
Switch to WPS Office to Avoid Mac Excel Glitches
If Microsoft Excel continues to experience frustrating keyboard glitches on your Mac, consider switching to WPS Office. It offers a lightweight, highly compatible alternative that works seamlessly on macOS without slowing down your system or dropping keyboard inputs.
- 1. Download and Install WPS Office: Visit the official WPS website, download the Mac version, and follow the straightforward installation prompts.
- 2. Open Your Excel Files: Launch WPS Spreadsheets and directly open your existing .xlsx or .xls workbooks.
- 3. Edit Without Interruptions: Enjoy a smooth typing and editing experience with full keyboard functionality, completely free from previous glitches.

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.
