Formatting comments

Excel for Microsoft 365 has changed how you work with comments, and now they are called notes.

	-  Notes in cells are indicated as little red triangles. By default, notes are displayed in a rectangular box with a yellow background.
	-  Comments are distinguished by little purple comment indicators.

See How to hide/display note and comment indicators for more details.

You cannot change the format of comments because all comments are shown in the separate pane (like the one shown above) with threads or on the Comments pane:
