Unprotect Excel Worksheets – A Guide to Remove Excel Password

Excel worksheets frequently contain sensitive information, whether it’s a company’s financial data or personal information about hundreds or thousands of employees. That makes their protection vital to the security of that information.

But what if you frequently work with a protected file and are tired of constantly inputting a password, or if you want to unprotect an Excel worksheet that doesn’t include sensitive data?

This Excel worksheet protection removal guide aims to resolve that. Stay around as we explore the methods for unprotecting sheets on Excel, teach you to remove worksheet protection, and examine a tool for unprotecting Excel worksheets online.

Part 1. What Is a Protected Excel Worksheet?

Due to their sensitive nature, Excel worksheets are often protected. At its core, a protected Excel worksheet is a spreadsheet (XLS or XLSX) file with a password to prevent accidental changes and unauthorized tampering with the file’s data.

Unlike workbook protection, which protects the entirety of an XLS or XLSX file, protecting an Excel worksheet refers to adding a password only for a single sheet or tab. That lets users open the Excel file but prevents them from accessing a specific tab at the bottom that may contain sensitive information.

Contrary to popular belief, it’s not a surefire way of preventing access. After all, a protected Excel worksheet isn’t entirely secure, and anyone who knows what they’re doing with VBA can crack the password in a few minutes, especially on Excel versions older than 2010.

Part 2. How to Unprotect an Excel Worksheet With/Without a Password?

The process of unprotecting a worksheet differs depending on whether you know the password. If you do, it’s a matter of a few clicks. However, you can also unprotect an Excel worksheet without a password, and we’ll show you how to perform both tasks below. Let’s dive in.

Using Excel When You Know the Password

Unlocking worksheets in Excel when you have the password is as easy as locking them in the first place. It’s often a process you can complete in a few seconds, and you can follow these steps to unprotect a worksheet with the password:

Step 1: Open your Excel file and find a sheet you want to unprotect.

Step 2: Right-click the sheet tab at the bottom and tap the Unprotect sheet option.

Step 3: Input your password and click OK.

You can also do this by navigating to the Review tab and clicking the Unprotect Sheet button. Alternatively, head to the Home tab and click Cells > Format > Unprotect Sheet in the drop-down menu.

3 Methods Used for Excel Unprotection without Password

Using a Visual Basic Script in Excel

Not knowing the password certainly changes things, but unlocking an Excel worksheet without a password is still possible. All you need to do is use a Visual Basic script in Excel, also known as VBA code or VBA macro. Here’s how:

Step 1: Launch Excel on your computer and select the password-protected sheet by selecting its tab at the bottom of the window.

Step 2: Hit the ALT + F11 keys on your keyboard to open Visual Basic Editor.

Step 3: Right-click your Excel workbook in the left sidebar and tap Insert > Module.

Step 4: When a window appears, input the following code.

Step 5: Tap the F5 key to run this Excel worksheet password breaker. The Excel VBA unprotect worksheet macro will output a fake password.

Step 6: Once you see it, tap OK to unprotect a worksheet without a password.

Note: As you can see in the VBA code above, the password-protected worksheet has to be the currently active sheet to unprotect it with the Excel worksheet password breaker.

Furthermore, the Excel VBA unprotect worksheet macro only works for Excel 2010 and older versions. After all, Microsoft has significantly improved its encryption algorithms for newer versions of Office.

Using Google Sheets

Google’s alternative to Microsoft Excel, Sheets, is another fantastic method for unprotecting Excel worksheets without a password. Here’s a quick guide for it:

Step 1: Open the Google Sheets web app in a browser and head to File > Open to upload your protected XLS or XLSX file.

Step 2: Check whether the password protection has been lifted and ensure you can edit the sheet.

Step 3: If it worked, head to File > Download as > Microsoft Excel (.xlsx) and save it as a new Excel file.

Note: This software alternative doesn’t care about older Excel’s rules. As a result, it automatically bypasses 2010 and older Excel’s worksheet password protection, making this method incredibly effective. However, it doesn’t work with many newer versions of Excel.

Using Zip and Notepad

A combo of an archiving utility and the built-in Notepad program can also unlock Excel worksheets without a password, and here’s how you can try this method yourself:

Step 1: Open File Explorer and find the password-protected Excel file.

Step 2: Tap View > Show > Image name extensions to see the .xls and .xlsx extensions on your Excel files.

Step 3: Select your protected Excel file, hit F2 to rename it, and change its extension from .xls or .xlsx to .zip. Tap Yes to confirm.

Step 4: Open the ZIP file with WinZip, WinRAR, or 7-zip.

Step 5: Go to xl > worksheets and drag-and-drop the XML file of the protected sheet to the Desktop.

Step 6: Open the extracted XML file with Notepad.

Step 7: Tap CTRL + . to search for “protect” and find the part of code that starts with “” and delete it.

Step 8: Drag and drop the edited XML file from the Desktop into the ZIP program.

Step 9: Close the ZIP app and change the extension from .zip to .xls or .xlsx.

Note: It’s highly recommended that you create a copy of the XLS or XLSX file before you attempt this. While the ZIP file method works most of the time, it can also corrupt your Excel spreadsheets and cause data loss.

Part 3. How to Unprotect Excel Worksheets Online?

The methods above vary considerably regarding their effectiveness at unlocking Excel worksheets without passwords, prompting many users to look into online services that promise to unlock Excel files. Thus, you can also unprotect Excel worksheets online with dedicated password removal services.

Using an Online Password Removal Service

While dozens of websites offer such services, we’ve found LostMyPass incredibly effective, while the service’s transparent success rates and pricing are undoubtedly a plus. Using it is a breeze, and here’s what you’ll need to do to unprotect Excel worksheets online:

Step 1: Visit the LostMyPass website and head to File Types > MS Office Excel.

Step 2: Complete the CAPTCHA to agree to the website’s terms and conditions, then drop a protected Excel file into the field to upload it.

Step 3: Give LostMyPass a few minutes to unlock the file. If it’s successful, you can save it to your device by tapping the Download Unlocked File button.

Note: You can unprotect Excel worksheets online for free if they have weak and short passwords, but the website states that your chances are roughly 22%. Stronger passwords will require getting the paid version of the tool, but they also increase your chances to ~61%.

However, it’s recommended that you avoid online password removal services if your Excel files contain sensitive data. Even the most secure tools are vulnerable to online attacks and might leak your sensitive information during uploads and downloads. They can also corrupt your data during password removal.
