Can You Change Excel Worksheet Tabs Back to Rectangular?
Question details
The user wants to know if it is possible to revert the new rounded worksheet tab design in Excel back to the traditional rectangular tabs.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Customizing the Excel workspace interface after noticing a design change in a recent Microsoft Office version.
- Observed behavior
- Worksheet tabs are displaying with rounded corners instead of the traditional rectangular shape, and there is no visible setting to change them back.
Note that Microsoft frequently updates the user interface for Office 365 and newer versions, and these visual changes are often applied universally without built-in toggle options for legacy designs.
Understanding the New Excel Interface Limitations
Clarify that Microsoft Excel does not offer a built-in feature or setting to revert to rectangular tabs.
Microsoft has updated the Office interface to feature rounded corners on worksheet tabs, aligning with the Windows 11 visual design language. Currently, Excel does not provide any setting, registry hack, or toggle to restore the older rectangular appearance.
Attempting to roll back to a previous software build might temporarily change the appearance, but auto-updates will eventually revert the interface to the rounded design. It is safer to adapt to the new UI or use an alternative office suite if the design heavily impacts your workflow.
Recognize that the rounded worksheet tabs are a permanent part of the updated Microsoft Office UI design and cannot be natively modified.
If you strongly prefer rectangular tabs, you can submit feedback by navigating to Help > Feedback in the Excel ribbon and letting Microsoft know your UI preference.

Frequently Asked Questions
Why did Microsoft change the Excel tabs to rounded corners?
Microsoft updated the Office suite interface to align with the visual design language of Windows 11, which heavily features rounded corners across applications, windows, and system menus to create a softer, more modern look.
Is there a registry edit to bring back rectangular tabs in Excel?
No, there is currently no known Windows registry edit or hidden developer setting that can revert the worksheet tabs back to their rectangular shape in the newer builds of Microsoft Excel.
Can I use a third-party add-in to change the tab shape in Excel?
Third-party add-ins typically cannot alter the core UI elements of Excel, such as the shape of the worksheet tabs. Add-ins are generally limited to adding functional features or side panes rather than modifying hardcoded Microsoft interface designs.
