Recovering Lost Excel Worksheet Password
Launch Microsoft Excel and open the workbook containing the password-protected worksheet.
Navigate to the Search Box and type in Protect Sheet. If it is password protected, you will be prompted for the worksheet password.
Since you’ve forgotten the password, we’ll explore methods to recover or test the worksheet without it.
Now, let’s save a copy of the password-protected worksheet to avoid any potential data loss. Go back to File Explorer and Right-click on your file to Copy.
Then, Right-click again on an empty space in the folder to Paste a copy of the file.
As you can see, a duplicate of the worksheet has been saved.
Left-click once on the duplicate worksheet file. Pause for a second. Then, click once again. Highlight the “xlsx” extension.
Note: If you can’t see the file extension, go up to the View tab, then click on Options.
From there, click on the View tab, and make sure the “Hide extensions for known file types” is unchecked.
Replace the “xlsx” extension name with “zip” and hit Enter.
Click Yes when prompted with this message:
As you can see, the Excel icon has been changed to the zip file icon.
Click the Extract button to reveal a new pop-up window displaying the file contents.
Double-click on the zip file and click on the XL folder.
Find the Worksheets folder within the XL directory, which contains individual worksheets labeled “sheet1.xml,” “sheet2.xml,” and so on.
Right-click on sheet1.xml, go to Copy.
Then, Paste a copy of sheet1.xml onto the Desktop.
From there, go to the Notepad application. Go to File, Open, and Desktop.
Go down to where it says Text Documents and click All Files.
Double-click on the file.
The coding text may look a bit complex. But we don’t need to know how to read any of these.
Click CTRL + F on your keyboard to do a text search. Type in the word “protect”
Go to Find Next. As you can see, the word “protect” will be highlighted.
We will be looking for the character “<.” It is beside “sheetProtection.” Identify the end of this code by locating the first “>” following it.
Highlight and delete all text within this code, starting from “<” and ending with “>” in Notepad.
Save the modified XML file by clicking the File button in the top left corner of Notepad and selecting Save.
Right-click on the file on the Desktop and go to Cut.
Go back to File Explorer. Right-click, then go to Paste.
You will be prompted with this message:
Select Copy and Replace.
Hit the back button 3 times until you are back to where we started.
Click the zip file. Highlight “zip” and replace it with “xlsx.” Press Enter.
Click Yes on the warning message.
Finally, when you double-click on the xlsx file, you will be able to access your spreadsheet without requiring a password.
To verify that it is no longer password-protected, head over to the search bar. Type in “protect.”
Go to Protect Sheet.
As you can see, you are now given the option to put the password in. Meaning it is no longer password-protected.
Recovering Lost Excel Workbook Password
Removing the password protection from an Excel Workbook is very similar to the method we used for the worksheet. With a few key differences:
Launch Microsoft Excel and open the workbook.
Navigate to the Search Box and type in “Protect Workbook.” If it is password protected, you will be prompted for the workbook password.

Then, Right-click again on an empty space in the folder to Paste a copy of the file.
As you can see, a duplicate of the workbook has been saved.
Left-click once on the duplicate workbook file. Pause for a second. Then, click once again. Highlight the “xlsx” extension.
Note: If you can’t see the file extension, go up to the View tab, then click on Options.
