Dark mode has been one of the most highly requested features, so there was plenty of excitement when Microsoft introduced it in Windows 10. This mode offers both aesthetic appeal and practical benefits, particularly for eye health, especially on devices with OLED screens.
However, Microsoft took longer to roll out a native dark mode for its suite of Office tools. Even when it was finally introduced, the implementation—especially in Excel—fell short of user expectations.
Thankfully, Microsoft has now confirmed that it is actively working to enhance Excel’s dark mode for Windows. This update will address lingering aesthetic issues and provide a more polished experience. Below, we’ll share further details on these improvements.
Microsoft confirms that Excel for Windows will receive dark mode improvements
As previously mentioned, dark mode has become a highly sought-after feature due to its benefits for eye health. It allows users to spend extended periods in front of OLED monitors with reduced eye strain when using applications in dark mode.
Additionally, dark mode improves energy efficiency on devices with OLED screens, as darker pixels consume less power. On top of these practical advantages, dark mode also offers a sleek and modern aesthetic that many users appreciate.
Microsoft introduced its Office programs’ dark mode in Windows 10 and Windows 11. While the implementation was well-received in some applications, others, like Excel, lacked the same level of refinement. However, this is about to change, as confirmed by insights shared by Thurrott.
Previously, switching from light to dark mode in Excel would leave the cells displayed in white while the rest of the interface turned black. This inconsistency was a frequent criticism of Excel’s dark mode. Thankfully, Microsoft is addressing this issue with a new update that significantly improves the feature’s functionality and appearance.
After installing this update, currently available through the Office test channels, the interface, and the cells will adopt a dark theme, creating a cohesive and polished dark mode experience.
The update is part of Build 18508.20000 for users in the Office test channel. Those using the stable version must wait slightly longer for the feature to roll out more broadly.
Additionally, Microsoft has announced via the @Microsoft365Insider account on X (formerly Twitter) that dark mode is also coming to the web version of Excel. This is excellent news, as it aligns Excel with other Office web tools like Word.
It’s now waiting for Microsoft to extend dark mode improvements across the entire operating system. Windows 10 and the latest Windows 11 still have some areas and interfaces lacking full dark mode support.
