Update macOS and Web Browsers to the Latest Versions

Updating your system and browsers resolves known rendering conflicts between macOS Ventura and web applications.

Excel for the web relies heavily on your browser's rendering engine and the underlying operating system. Display issues, such as excessive empty space in toolbars, are often caused by temporary incompatibilities in older software versions.

Click the Apple menu in the top-left corner of your screen, select 'System Settings', go to 'General', and click 'Software Update'. Install any available updates.

2
Update Safari

Safari updates are bundled with macOS updates. By completing the macOS update in the previous step, Safari will automatically be updated to the latest version.

3
Update Google Chrome

Open Google Chrome, click the three-dot menu icon in the top-right corner, select 'Help', and click 'About Google Chrome'. Chrome will automatically check for and install available updates. Relaunch Chrome when prompted.

4
Reload Excel for the Web

After updating, open your browser, navigate back to your Excel workbook online, and verify if the bottom ribbon size has returned to normal.

Frequently Asked Questions

Why is the bottom ribbon suddenly taking up so much space in Excel for the web?

This is typically caused by a rendering conflict between the specific version of your web browser (like Safari or Chrome) and macOS Ventura. The browser fails to scale the web page UI elements properly, resulting in excessive padding. Updating your software is the best fix.

Can I collapse the ribbon in Excel for the web to gain more screen space?

Yes. You can click the downward-facing arrow in the lower-right corner of the ribbon to switch to a 'Single-line ribbon', which significantly reduces the vertical space the toolbar consumes on your screen.

Will clearing my browser cache fix the oversized ribbon issue?

Sometimes, corrupted cache files can cause web applications to load incorrectly. You can try clearing your cache in Chrome by pressing Cmd+Shift+Delete, or in Safari by navigating to Settings > Privacy > Manage Website Data, and then refreshing the page.

Are the desktop versions of Microsoft Excel affected by this Mac display bug?

No. Desktop applications like Microsoft Excel for Mac or WPS Office have their own native rendering engines and are generally unaffected by browser-specific display bugs found in Safari or Chrome.
