How do you add a comment to a cell in Excel?

Adding a comment to a cell in Excel is accomplished by right-clicking the cell and selecting 'Insert Comment' (now known as 'New Comment' in more recent versions). This action opens a text box where you can type your comment, which is then attached to the cell. Comments serve as a useful tool for providing additional context, notes, or clarifications about the data within that particular cell without cluttering the spreadsheet layout.

The method of right-clicking and selecting 'Insert Comment' makes it straightforward and is a common convention in many software applications, ensuring that users can easily find and utilize the commenting feature. This functionality is particularly useful in collaborative environments where multiple users may need to understand or provide input on different aspects of a spreadsheet.
