Learn how to unprotect Excel or remove worksheet password

by | April 7th, 2017

This is a Step-by-step blog on how to unprotect excel spreadsheet without using any software. This includes changing file extension and manipulating its constituents to get an unprotected excel file.

Almost ALL Excel users wish at some point or the other felt the need of some magic to “Unprotect Excel Sheet” password so that they can see the formula and make changes.

Please note that this hack is to unprotect the worksheet password and not the workbook password *

A lot of us take the help of Google. You are redirected to 100’s of sites who ask you to download some software.

1) Some of those software apps will display only first 2 or 3 characters of the Excel password (trial version).

2) Some will install interesting pictures and set your default browser homepage to some “one who can’t be named” website. You get the drift!

3) Some (paid versions) will display many hours of computing time to crack the Excel password in case the password is not a simple dictionary word. (BTW dictionary word passwords can be easily cracked using a technique called “Dictionary attack”. Rest needs “Brute Force attack” technique) but nothing will match the MS Office Training we provide you.

NOW, let me start taking you through the process of the GOD MODE Excel Password trick.

What do you require to begin to unprotect an excel spreadsheet?

A protected sheet (or protect your this as show below)

In Excel Click on Review tab then click on Protect sheet - Unprotect sheet

Popup comes out to make changes click on unprotect sheet in the review tab

Step 1: Enable display of file extension names

This will be required to change the file extension. For example from Budget.xlsx to Budget.zip and back to Budget.xlsx. [“Control Panel” – “Folder Options” – “View” tab – Uncheck “Hide Extension for know file type”]

Go to Control Panel then Select Folder Options for Unprotect Sheet

In the Folder Options then Select View then go to Advanced Settings Untick the Hide extension for Known file types for Unprotect Sheet

Step 2: Change the extension of you Excel file from .xlsx to .zip

Change the extension of file from .xlsx to .zip

Step 3: Open the zipped file and extract the relevant XML file from the zipped file and follow the picture trail

Open the zipped file and extract the relevant XML file from the zipped file - Unprotect Sheet

Extract these XML files outside the folder. They represent the worksheets in the Excel file. Modified codes using simple “Notepad”. The modified XML file should be put again in the zipped file to replace the old XML files.

Step 4: Open the XML file in a notepad and delete the following tags marked in double quotes below

v. 2007-10 – “sheetProtection password=… />”

v. 2013 – “sheetProtection algorithmName=…/>”

Open the XML file in a notepad and delete the following tags marked in double quotes for Unprotect Sheet

Now save the XML file and put it back in the zipped folder from the extracted location. It will replace the original XML files.

Last Step: Close the zipped file and change the extension back to .xlsx (reverse of Step 2 above)

Enjoy the GLORY my friend 🙂 – The relevant sheets for which corresponding modified XML files will not ask for any Excel password anymore
