When clicking the Protect Structure option, what is the likely intent?

The intent behind selecting the Protect Structure option is to restrict modifications to the workbook structure. When this feature is activated, it prevents users from making changes that could alter the foundational aspects of the workbook—such as adding, deleting, or renaming worksheets. This is particularly important in collaborative environments where multiple users may have access to a document, and you want to maintain control over how the workbook is organized and what its overall structure looks like.

Using this feature helps ensure that the integrity of the document is preserved and that users cannot inadvertently or intentionally disrupt its intended framework. This is especially useful for protecting sensitive data, ensuring compliance with organizational standards, or maintaining the document for future use in its original format.
