Protecting the Structure of a Workbook

 To protect the structure of a workbook, including its sheets, you can use Excel's "Protect Workbook" feature. This prevents users from adding, deleting, hiding, or renaming sheets, as well as changing the structure of the workbook. Here's how to do it:

Open Excel Workbook: Launch Microsoft Excel and open the workbook you want to protect.

Navigate to the Review Tab: Click on the "Review" tab in the Excel ribbon at the top of the window.

Protect Workbook Structure:

In the "Changes" group, click on the "Protect Workbook" button.

From the dropdown menu, select "Protect Structure and Windows."

Set Password (Optional):

If you want to password-protect the workbook structure, enter a password in the "Password" field.

Confirm the password in the "Confirm Password" field.

Choose Protection Options:

In the "Protect Structure and Windows" dialog box, you can choose various options to allow specific actions, such as inserting, deleting, renaming, or hiding sheets.

Make sure to uncheck any options that you want to restrict users from performing.

Click "OK":

Click "OK" to apply the protection settings and protect the structure of the workbook.

After protecting the workbook structure, users won't be able to perform the specified actions without unprotecting the workbook (if it's password-protected, they will need to enter the password). This method helps ensure that the structure of your workbook remains intact and prevents accidental or unauthorized changes to the workbook's layout and organization.
