One of the most important things one can do to protect Excel files is to apply protection to them. This can be important especially if the data in the workbook is sensitive or confidential. In this article, we will discuss various ways to protect Excel workbooks and how to apply them.

How to Protect Workbook (Workbook Level Protection) in Excel File

Workbook protection is a security feature that protects the entire workbook against unauthorized access, modifications, or even viewing. It is one of the best ways to prevent unauthorized access to your data. To apply workbook protection, follow these steps:

1. Open the Excel workbook that you want to protect.
2. Click on the “Review” tab on the ribbon and select “Protect Workbook” in the “Changes” group.
3. Select “Protect Structure and Windows” option. You can also set a password for the workbook by entering a password in the “Password to protect workbook modifying” field.
4. Click “OK” to apply the protection.

Once the workbook protection is applied, users will not be able to rename, delete, or add sheets, view hidden sheets, or modify the workbook in any way. However, the users will still be able to save changes to cells, sort and filter data, and make basic formatting changes.

How to Protect Workbook (Workbook Level Protection) in Excel File with Password

In some cases, you may want to apply workbook protection with a password. This will prevent unauthorized users from accessing the data in the workbook. To apply workbook protection with a password, follow these steps:
