Microsoft Excel is a powerful tool that can be used for a variety of tasks, from managing finances to creating charts and graphs. However, like any other software, Excel can be vulnerable to attack. In this article, we will discuss some tips on how to protect your Excel workbook from unauthorized access. First and foremost, make sure that you have a strong password protecting your workbook file. This is especially important if you plan on sharing your workbook with others. Additionally, make sure that you keep your workbook up-to-date with the latest security patches. Microsoft regularly releases updates to address security vulnerabilities in its products. Another way to protect your workbook is to encrypt it using the Windows Encryption feature. This will help prevent unauthorized access to the file while still allowing you to use it if necessary. Finally, always keep track of which files are open in Excel and make sure that they are closed when you are finished using them so that others cannot access them without your permission. ..
Whether you want to make structural changes or modify the content in your Microsoft Excel workbooks, you’ll have to unprotect those items first. We’ll show you how to do just that.
If you used a password to protect your Excel items, you’ll need that password in the unlocking procedure below, so keep that handy.

Unprotecting a Workbook vs. Unprotecting a Worksheet
If you’d like to make structural changes to your workbook, like adding, moving, deleting, hiding, or renaming your worksheets, you’ll have to unprotect your workbook (as opposed to unprotecting a worksheet). Doing that unlocks the options to make the above-mentioned changes to your workbook.
In case you’re looking to modify the data in your worksheet, such as changing the content of a cell, you’ll have to unprotect your sheet. This allows you to add and remove content from your worksheet.
Either way, it’s easy to unprotect your items in Excel as we’ll explain below.
Unprotect an Excel Workbook
To be able to make structural changes to your workbook, first, launch your spreadsheet with Microsoft Excel.
In Excel’s ribbon at the top, click the “Review” tab.
On the “Review” tab, from the “Protect” section, choose “Protect Workbook.”
If you didn’t use a password to protect your workbook, your workbook is now unprotected.
In case you used a password for protection, then in the “Unprotect Workbook” box that opens, type that password and click “OK.”
Your workbook is now unlocked and you can add, remove, delete, hide, and rename worksheets in it. Enjoy!
