- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Viewing or editing spreadsheet data in Microsoft Excel.
- Observed behavior
- Excel worksheets display black backgrounds with light-green text. Standard troubleshooting methods like reinstalling Office or altering Windows graphic settings do not resolve the issue, while other Microsoft 365 applications remain unaffected.
Check your Windows accessibility settings to ensure 'High Contrast' mode is not enabled, as operating system settings can occasionally override application themes.
Adjust the Office Theme Settings
Modify the built-in Microsoft Office Theme to restore the standard white worksheet background.
In most cases, this display anomaly is caused by the Office Theme being set to 'Dark Gray' or 'Black', which inadvertently forces the cell backgrounds to invert. Switching the theme back to 'Colorful' or 'White' will instantly resolve the problem without the need to reinstall the software.
Launch Microsoft Excel. Click on the 'File' tab located in the top-left corner of the window, and then select 'Options' at the bottom of the left-hand navigation pane.
In the Excel Options dialog box, verify that you are on the 'General' tab. Scroll down to the section labeled 'Personalize your copy of Microsoft Office'.
Click the dropdown menu next to 'Office Theme'. If the current selection is set to 'Dark Gray', 'Black', or 'Use system setting', change it to 'Colorful'.
Click the 'OK' button at the bottom of the window to apply your new settings. Close and restart Excel to confirm that the worksheet background has returned to normal.

Frequently Asked Questions
Does the black background affect how my spreadsheet prints?
No. The Office Theme only alters the graphical user interface on your screen. Unless you have manually applied a black fill color to the individual cells, your document will print with a standard white background.
Why did my Excel theme change to dark mode automatically?
Excel themes can sometimes change on their own if the Office Theme is configured to 'Use system setting' and your Windows or macOS computer switches to dark mode. It can also occur if theme settings are synchronized from another device logged into the same Microsoft 365 account.
What if changing the Office Theme doesn't fix the black screen?
If adjusting the theme doesn't resolve the black cells, verify that Windows High Contrast mode is turned off. You can also try disabling hardware graphics acceleration in Excel's Advanced settings, or updating your computer's graphics drivers.
Can I use dark mode in WPS Spreadsheet?
Yes, WPS Office offers a dedicated Dark Mode and a customized Eye Protection mode. These settings allow you to comfortably view spreadsheets in low-light environments without causing unintended display errors to the cell content.
