Hi DB
Thank you for reaching out Q&A forum regarding the recent changes in Excel's appearance. We understand that unexpected updates to the interface, such as modifications to the ribbon, tabs, or theme, can be disorienting, especially when you're accustomed to a particular layout. These changes are typically part of Microsoft's ongoing efforts to enhance usability and align Office applications with modern design standards, particularly those introduced with Windows 11. To better assist you, it would be helpful if you could share a screenshot of your current Excel interface. This will allow us to better understand the changes you're experiencing and offer more specific guidance.
If you're using Excel 365, you can customize the look and feel to better suit your preferences. Simply navigate to File > Options > General, where you'll find settings to adjust the Office background and Office theme. These options may allow you to restore a familiar appearance or explore new visual styles.

Please rest assured that while the interface may evolve, the core functionality of Excel remains consistent.
