Excel 2019 does not fully support a Dark Mode for its content area as Office 365 does. While Excel 2019 includes some customization options, its support for Dark Mode is limited primarily to the application’s interface rather than the spreadsheet content itself.

Dark Mode in Excel 2019 for macOS

Here's how you can adjust Excel 2019 to get the closest experience to Dark Mode:

1. System-Wide Dark Mode (macOS Sonoma)

1. Open System Preferences:
• Click the Apple menu in the top-left corner of your screen.
• Select System Preferences.
2. Go to Appearance:
• Click on General.
3. Select Dark Mode:
• Choose Dark under the “Appearance” section.

This will affect the overall appearance of macOS and compatible applications, including Excel. However, Excel 2019 may not fully adopt Dark Mode for its content area.

2. Office Theme in Excel 2019

1. Open Excel 2019:
• Launch Excel from your Applications folder or dock.
2. Access Preferences:
• Click Excel in the top menu bar and select Preferences.
3. Choose General:
• In the Preferences window, go to General.
4. Set Office Theme:
• Look for Personalize section.
• Find the Office Theme dropdown menu.
• Select Dark Gray or Black if available.

Note: Excel 2019’s theme options are more limited compared to Office 365, and the theme mostly affects the interface rather than the content of the spreadsheets.

3. Customizing Spreadsheet Appearance

Since Excel 2019 does not offer a comprehensive Dark Mode for spreadsheet content, you can manually adjust your spreadsheets for better visibility:

1. Change Background Color:
• Select the cells or range you want to modify.
• Go to the Home tab.
• Click the Fill Color icon (paint bucket) and choose a dark color for the background.
2. Adjust Font Color:
• Click the Font Color icon (A with a color underline) and choose a light color (e.g., white) to contrast with the dark background.

4. Consider Upgrading

If Dark Mode and enhanced accessibility features are crucial for your workflow, consider upgrading to Microsoft 365 (formerly Office 365). Microsoft 365 provides better support for Dark Mode and other modern features across its applications, including Excel.

Summary

• System-Wide Dark Mode: Apply through macOS settings; affects Excel’s interface but not content.
• Office Theme: Set to Dark Gray or Black in Excel Preferences, though content visibility may still be limited.
• Manual Customization: Adjust cell and font colors for better readability.
• Upgrade to Microsoft 365: For enhanced Dark Mode support and additional features.
