Does Excel Support Dark Mode for Worksheet Cells? Fixes & Workarounds
Question details
The user is trying to find a way to apply dark mode to the actual worksheet cells in Excel without permanently altering the cell fill colors for colleagues viewing the shared workbook.

- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Working in low-light conditions on a shared spreadsheet where the bright white cells cause eye strain.
- Observed behavior
- Excel's built-in dark theme only darkens the application interface (ribbons, menus, and borders) but leaves the worksheet cells stark white.
Ensure you have already enabled the application-level Dark Mode by navigating to File > Account > Office Theme and selecting 'Black' or 'Dark Gray', as the following workarounds only address the cell area.
Apply a Dark Background Image (Local Workaround)
Insert a dark image as the sheet background to darken the canvas visually without changing the actual cell fill colors.
Since Microsoft has not officially released a native dark mode for the cell grid, using a dark background image acts as a visual overlay. It darkens your view while allowing you to change font colors temporarily. Remember to remove the background before sharing the final file if you do not want others to see it.
Open MS Paint or any image editor, fill the canvas with a dark gray or black color, and save it as an image file on your computer.
Open your Excel workbook, navigate to the 'Page Layout' tab on the ribbon, and click 'Background'.
Choose 'From a file', locate the dark image you just created, and insert it. Your worksheet cells will now display over the dark background.
Select all cells (Ctrl + A) and change the font color to white or light gray from the 'Home' tab so the text remains readable against the dark background.

Use Trusted Third-Party Add-ins
Install external add-ins designed to toggle a dark theme on the worksheet grid dynamically.
Use WPS Office for Built-in Eye Protection
If Excel's bright canvas causes eye strain and workarounds are too cumbersome, consider switching to WPS Office. It provides high compatibility with Excel files and features a native Eye Protection Mode that darkens the editing area locally without altering the document format for your colleagues.
- 1. Open your spreadsheet: Launch WPS Spreadsheet and open your existing .xlsx file.
- 2. Navigate to the View tab: Click on the 'View' tab located in the top ribbon menu.
- 3. Enable Eye Protection Mode: Click the 'Eye Protection Mode' icon (shaped like an eye). The worksheet cells will immediately switch to a softer, darker background, reducing eye strain.

Frequently Asked Questions
Will Microsoft ever add an official dark mode for Excel cells?
As of now, Microsoft has not officially announced a native dark mode that applies directly to the worksheet canvas in Excel, although it remains a highly requested feature on the Microsoft Feedback portal.
Does changing the cell fill color to black affect other users?
Yes. If you manually change the cell fill colors to black and the font to white, those formatting changes are permanently saved in the document. Anyone else opening the shared workbook will see the black cells.
How do I turn on Excel's standard interface dark mode?
To enable dark mode for the application menus and ribbons, go to File > Account. Under the 'Office Theme' dropdown, select 'Black' or 'Dark Gray'. This does not affect the worksheet cells.
