Frequently Asked Questions

Why does Excel keep changing my selected font colors?

Excel may change font colors automatically if a custom theme is corrupted, if a conditional formatting rule is overriding your manual formatting, or if there is an underlying issue with your Microsoft Office installation files.

What is the difference between Online Repair and Quick Repair in Microsoft Office?

Quick Repair checks and replaces missing or corrupted files locally without needing an internet connection. Online Repair reinstalls Office completely and requires an active internet connection, making it much more thorough for fixing stubborn application bugs.

How do I customize and save theme colors in Excel?

To customize theme colors, navigate to the Page Layout tab, click on Colors in the Themes group, and select Customize Colors at the bottom of the drop-down menu. From there, you can define specific hexadecimal or RGB colors for text, backgrounds, and accents.
