How to Fix Excel Bouncing in Dock and Not Opening on Mac
Question details
The user needs to resolve an issue where Microsoft Excel crashes at startup on macOS, indicated by the icon continuously bouncing in the Dock without launching.

- Product
- Microsoft Excel for Mac
- Device & OS
- macOS
- Scenario
- Attempting to launch the Microsoft Excel application from the Dock on an Apple Mac computer.
- Observed behavior
- The Excel icon bounces continuously in the Dock but the application ultimately fails to open, crashing during the startup process.
Before troubleshooting, ensure you have force-quit Microsoft Excel if it is unresponsive (Option + Command + Esc) and verify that your macOS version is fully up to date.
Reset Excel by Clearing Container Preferences
Moving the Excel container folder to the Desktop clears corrupted application caches and preferences, which is the most common fix for startup crashes on Mac.
macOS isolates app data in specific 'Container' folders. If the files inside the Excel container become corrupted, the app will fail to load properly and bounce in the dock indefinitely. Removing this folder forces Excel to generate clean, fresh preference files upon the next launch.
Click the Apple menu and select 'Force Quit', or press Option + Command + Esc. Select Microsoft Excel and click 'Force Quit' to ensure the app is completely closed.
Click on the Finder icon in your Dock. From the top menu bar, select 'Go' and then click 'Go to Folder...', or simply press Command + Shift + G on your keyboard.
In the search box that appears, carefully type '~/Library/Containers' (without quotes) and press Return.
Look for a folder named 'Microsoft Excel' (or 'com.microsoft.Excel' on older macOS versions). Click and drag this specific folder to your Mac's Desktop.
Click the Apple menu and select 'Restart'. Once your Mac boots up, click the Excel icon in the Dock to see if it opens successfully. If it does, you can safely delete the folder you moved to the Desktop.
Boot Your Mac in Safe Mode
Starting your Mac in Safe Mode runs automatic directory checks, clears system caches, and prevents background software conflicts that might be stopping Excel from opening.

Frequently Asked Questions
Will moving the Microsoft Excel folder to the desktop delete my spreadsheets?
No. Moving the 'com.microsoft.Excel' or 'Microsoft Excel' container folder only resets the application's configuration preferences and temporary cache files. Your saved .xlsx files, templates, and personal spreadsheets remain completely unaffected.
Why does the Excel icon keep bouncing but never opens?
An application icon bounces in the macOS Dock to indicate that it is in the process of launching. If it continues bouncing infinitely and ultimately fails to open, it typically indicates that the application's preference files are corrupted, there is a background software conflict, or the installation itself is damaged.
What should I do if Safe Mode fixes the Excel bouncing issue?
If Excel opens flawlessly in Safe Mode, the issue was likely caused by corrupted system caches or a third-party background application conflicting with Excel. Try restarting your Mac normally. Often, simply booting into Safe Mode and back out clears the problematic cache automatically, resolving the issue permanently.
