- Scenario
- Attempting to highlight partial text inside a cell in a web browser to change its font, size, color, or apply bold/italics.
- Observed behavior

Verify whether you have a desktop spreadsheet application installed, as web-based Excel versions intentionally limit rich text editing capabilities.
Open the Workbook in the Excel Desktop Application
Use the desktop version of Excel to gain full access to rich text formatting tools for specific characters inside a cell.
Excel for the web does not support partial-text formatting. To change the font, color, or style of specific words within a cell, you must transition your active session to the fully-featured desktop application.
In the ribbon of Excel for the web, look for the 'Viewing' or 'Editing' button and select 'Open in Desktop App', or click the dedicated 'Open in Desktop App' button on the main menu.
Once the workbook opens in the desktop application, double-click the cell containing the text you want to format.
Highlight the specific portion of the text and use the Home tab on the ribbon to apply your desired font styles, colors, or bold formatting.

Format the Entire Cell Instead
If you must stay in the browser, you can apply formatting to the entire cell rather than partial text.

Frequently Asked Questions
Why is the font color disabled when editing text in Excel online?
Excel for the web lacks support for rich text formatting on partial cell contents. When you double-click a cell to enter text-editing mode, the formatting controls on the ribbon are intentionally disabled by design.
Will partial text formatting applied in desktop Excel show up in Excel for the web?
Yes. If you format specific words within a cell using a desktop app like Microsoft Excel or WPS Office, those formats will display correctly when viewing the workbook in Excel for the web, even though you cannot edit that specific formatting online.
Is there any browser extension to fix Excel online text formatting?
No, this is a core limitation of the Excel for the web application architecture. To apply partial cell formatting, you must use a desktop spreadsheet program.
