Part 2. How to Unlock an Excel Document With or Without a Password

When you are aware that you can unlock, you need to learn how to unlock. I will lead you through the cases where you have the password and those where you do not. I have personally done these, and they are not risky with files owned or used in the workplace.

Method 1. When You Know the Password

When you have the password, unlocking your Excel document is easy and safe. Excel has default tools that automatically strip protection, leaving your data and formatting intact. I use this method often whenever I need quick access to locked workbooks during deadlines. Follow these straightforward steps to unlock an Excel document with a password safely:

Step 1. Firstly, navigate to the "Review" option in the upper toolbar of your Excel.

Step 2. After that, choose the "Unprotect Sheet" or "Unprotect Workbook" option to proceed further.

Step 3. Lastly, enter the "Password" and hit the "OK" button to unlock the Excel document.

Method 2. When You Don't Know the Password

Sometimes we receive legacy files or shared documents where no one remembers the password. Read further to know how I safely unlock an Excel document without a password when it's truly necessary.

Change the File Extension

If the password is lost, I use file-structure editing to remove sheet protection. This technique modifies the workbook XML and safely deletes the sheet Protection tag. I also make sure that I first back up the file so that it does not get corrupted accidentally or lose its data. In order to apply this procedure and regain access to editing, follow the steps below:

Step 1. First, make a backup copy, right-click on the file, and choose the "Rename" option.

Step 2. Then, replace the ".xml" with "zip" and hit the "Yes" button in the dialog box.

Step 3. Lastly, open the file in a plain-text editor, remove the screen protection tag, and navigate to the "File" option to select "Save."

Use a VBA Script

When XML editing feels risky, I use a VBA script to disable the lock in Excel. This brute-force approach tries many common combinations and can unlock simple protections quickly. I recommend running this only on files you own to remain ethical and legal. Use the following concise steps to run a VBA unlocking macro safely on the workbook:

Step 1. First, open the "Protected Workbook," navigate to the "Developer" tab, and click on the "Visual Basic" to proceed.

Step 2. After that, in the VBA editor, right-click on your project, hover over "Insert," and click on the "Module."

Step 3. Lastly, enter the "Macro Script," hit the green "Run" button, and wait.

Conclusion

To sum up, unlocking Excel files no longer stresses me out. I've learned that with a few careful steps, I can unlock an Excel document without a password or remove it easily when I know the code. Once unlocked, I often export it to UPDF for markup, review, or safekeeping.
