- Device & OS
- macOS
- Scenario
- Adjusting row and column sizes to properly fit cell content without having to manually drag boundaries, specifically seeking a keyboard shortcut approach.
- Observed behavior

Create a Custom AutoFit Keyboard Shortcut in macOS
Since Excel for Mac lacks default Alt-key shortcuts, creating a custom macOS keyboard shortcut is the most efficient permanent solution for keyboard users.
macOS allows you to map custom keyboard shortcuts to specific menu commands for any application. By mapping the exact menu path for AutoFit, you can recreate a quick shortcut experience.
Click the Apple menu in the top-left corner of your screen and select System Settings (or System Preferences on older macOS versions).
Go to Keyboard, click on Keyboard Shortcuts, and then select App Shortcuts from the left sidebar.
Click the '+' button, choose Microsoft Excel from the Application dropdown, and type 'Format->Row->AutoFit' or 'Format->Column->AutoFit Selection' exactly as it appears in the Excel menu.
Click the Keyboard Shortcut box, press your desired key combination (e.g., Control+Option+A), and click Done.

Use the Boundary Double-Click Method
If you prefer using a mouse or trackpad, double-clicking the column or row boundary is the fastest native method requiring no setup.
Access AutoFit via Menu Bar Navigation
You can use macOS native menu bar shortcuts to navigate to the AutoFit command without touching your mouse.

Frequently Asked Questions
Why doesn't the Alt key work for ribbon shortcuts in Excel for Mac?
Microsoft Office for Mac does not natively support the Windows-style Alt-key ribbon navigation feature. Mac users must rely on standard macOS keyboard shortcuts, custom app shortcuts, or the menu bar navigation instead.
Can I AutoFit all columns in an entire Mac worksheet at once?
Yes. Click the 'Select All' triangle button in the top-left corner of your spreadsheet grid (where the row numbers and column letters intersect), then simply double-click any column boundary line.
Where can I request Microsoft to add Alt-key shortcuts to Excel for Mac?
You can submit feature requests or vote on existing ones through the official Microsoft Feedback Portal. Many Mac users have requested parity with Windows keyboard shortcuts there.
