Which button do you click to unprotect a worksheet?

To unprotect a worksheet in applications like Microsoft Excel, you need to click on the button labeled "Unprotect Sheet." This function specifically removes the protection that has been applied to a worksheet, allowing users to make changes to the content, formatting, and structure of that sheet without any restrictions.

When a worksheet is protected, users may be limited in their ability to edit or modify certain elements. By selecting the "Unprotect Sheet" option, you effectively disable any restrictions, enabling full access to the worksheet. This feature is crucial for scenarios where you initially want to secure a sheet from unintentional editing but later decide to allow modifications.

In contrast, the other options such as "Protect Sheet" would enable protection rather than remove it, while "Check for Issues" is typically used to review potential problems in the worksheet, and "Format Cells" pertains to adjusting how cells are displayed rather than altering sheet protection settings.
