What function does an edit pencil symbol have in a worksheet?

The edit pencil symbol in a worksheet indicates that the worksheet can be edited. This visual cue is essential for users as it helps them recognize that they have the capability to make changes to the data within that specific worksheet. When the pencil icon appears, it clearly communicates that the content is not locked or restricted, allowing users to add, modify, or delete information.

Understanding this symbol enhances the user experience by providing immediate feedback about the state of the worksheet, ensuring that users know when it is appropriate to input data.
