How to Fix Black Background and Green Text in Excel
Question details
The user is experiencing an abnormal display issue where Excel and parts of File Explorer show a black background with light-green text.

- Product
- Microsoft Excel
- Device & OS
- Windows
- Scenario
- Using Excel and navigating files when the display colors suddenly invert or change abnormally.
- Observed behavior
- The application interface displays a black background with green text, while other Microsoft 365 applications remain unaffected.
Save your current work and close all unnecessary applications. Since this issue might require restarting Windows Explorer or updating display drivers, having your files saved prevents data loss.
Check Windows High Contrast and Theme Settings
Sometimes Windows accessibility features or custom themes get stuck, causing abnormal colors in specific apps.
Even if High Contrast mode appears to be off, toggling the setting can sometimes reset a stuck display state that affects Excel and File Explorer.
Press Win + I to open Windows Settings, then navigate to Accessibility and select Contrast themes (or High contrast in older Windows versions).
Ensure the theme is set to 'None'. If it is already off, try selecting a contrast theme, applying it, and then setting it back to 'None' to reset the display state.
Go to Personalization > Colors in Windows Settings and ensure your default app mode is set correctly (Light or Dark) without custom accent colors forcing green text.

Restart Windows Explorer and Update Graphics Drivers
Display glitches affecting both Excel and File Explorer are often tied to the Windows Explorer process or outdated graphics drivers.
Run Excel in Safe Mode
If the issue persists only in Excel, a faulty add-in might be causing the display glitch.
Try WPS Office for a Glitch-Free Spreadsheet Experience
If Microsoft Excel continues to experience display issues like black backgrounds and green text, consider switching to WPS Office. It is a free, lightweight, and highly compatible alternative that offers a familiar interface without the heavy system resource drain.
- 1. Download the Installer: Visit the official WPS website and download the free installation package.
- 2. Install WPS Office: Run the downloaded file and follow the simple on-screen instructions to complete the setup.
- 3. Open Your Spreadsheets: Launch WPS Spreadsheet and seamlessly open your existing Excel files without losing any formatting.

Frequently Asked Questions
Why does my Excel background turn black randomly?
This is usually caused by a glitch in Windows High Contrast themes, an outdated graphics driver, or a conflict with a specific Excel add-in. Restarting Windows Explorer or updating your display drivers often resolves the issue.
How do I reset my Excel view settings to default?
You can reset the view by going to the View tab in the Excel ribbon and selecting 'Normal' under Workbook Views. If the entire application UI is affected, you may need to repair your Office installation via the Windows Control Panel.
Does Office Dark Mode cause green text?
Native Office Dark Mode typically uses white or light gray text. If you are seeing bright green text on a black background, it is almost certainly a Windows High Contrast theme overriding the application's default colors.
What should I do if turning off High Contrast doesn't work?
If toggling High Contrast off and on does not fix the issue, try updating your graphics card drivers in the Device Manager, or launch Excel in Safe Mode (using the 'excel /safe' command) to see if an add-in is causing the problem.
