You can add a comment to any cell to make your Excel spreadsheet easier to understand. This is handy any time you're sharing a spreadsheet with someone, to indicate how a complex formula works, or just to jot a note to yourself.
It's an unobtrusive way to add comments, that doesn't clutter up your spreadsheet.
Here's how to add a comment to a cell:
- The easiest way I've found is to right-click on a cell, and from the menu click on Insert Comment
- A small yellow box with your name and a blinking cursor appears. You can enlarge or smallify the comment box by dragging the handles on the edges of a comment box.
- Type your comment; it can be a maximum of 32,767 characters.
- Click anywhere outside of the comment box.
- A red triangle in the upper-right corner of the cell indicates your comment was set.
To see a comment, just hover your mouse cursor over the red triangle, and it will pop up.
