Video Timings and Methods Used:
00:00 Overview of Methods
00:50 Method 1: Get Lucky – find it within existing VBA code
02:50 Method 2: Remove with a VBA macro – can’t restore the password after
06:44 Method 3: Hack the File Code – Fastest and most likely to work, but most advanced

In this Microsoft Excel tutorial, I walk you through three proven methods to remove protection from a sheet when you don’t know the password. Whether you’re facing a locked Excel file or simply need to modify a protected sheet, this video gives you clear, actionable solutions to unlock and modify your spreadsheets without the need for a password. After watching, you’ll know how to unlock Excel sheets, make changes, and even reinstate protection—all without ever needing to know or recall the original password.

Here are the main topics covered in this tutorial:

Method 1: Checking for Passwords in VBA Code
In this first method, I show you how to search for password information within Excel’s VBA (Visual Basic for Applications) code. If the sheet is part of a macro-enabled workbook (xlsm), there’s a chance the password might be embedded in the VBA code. I walk you through how to open the VBA editor and search for any instances where the password might be exposed. If the password is hidden in the code, you can unlock the sheet instantly. This method is quick and easy if the VBA code contains the password.

Method 2: Using VBA Code to Crack the Password
When no password is found in the VBA code, I dive into a more technical approach using a brute force method. In this section, I show you how to use a custom VBA code to forcefully try every possible password combination until the protection is removed. You’ll learn how to run the code and how to handle any crashes that might occur during the process. While this method can take a significant amount of time (depending on the complexity of the password), it’s a reliable way to unlock a sheet without knowing the password.

Code not written by myself so use at your own risk. I have simply broken out onto separate lines to allow it to be run one loop at a time with stop breaks to avoid machine lockups.

Sub sbRemoveSheetPassword()
Dim i As Integer, j As Integer, k As Integer
Dim l As Integer, m As Integer, n As Integer
Dim i1 As Integer, i2 As Integer, i3 As Integer
Dim i4 As Integer, i5 As Integer, i6 As Integer
On Error Resume Next
For i = 65 To 66
For j = 65 To 66
For k = 65 To 66
For l = 65 To 66
For m = 65 To 66
For i1 = 65 To 66
For i2 = 65 To 66
For i3 = 65 To 66
For i4 = 65 To 66
For i5 = 65 To 66
For i6 = 65 To 66
For n = 32 To 126
ActiveSheet.Unprotect
Chr (i) & Chr(j) & Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
If ActiveSheet.ProtectContents = False Then
MsgBox /”Complete/”
Exit Sub
End If
Next Next Next Next Next Next Next Next Next Next Next Next
End Sub

Method 3: The Robust File Hack (ZIP Method)
For the most foolproof solution, I walk you through a method that involves manipulating the Excel file directly. By changing the file extension to a .zip file, I show you how to open the file’s contents, locate the protected sheet’s XML code, and remove the protection manually. This method is extremely effective and allows you to both remove the protection and reapply it with the exact same password. I also cover the steps to restore the protection once you’ve made your changes, ensuring that the Excel sheet remains secure after you’re done editing it.

By the end of this video, you’ll be equipped with three powerful ways to handle Excel sheet protection without needing to remember or know the original password. Whether you’re dealing with a locked spreadsheet or need to edit a file without compromising its security, you’ll have the skills to manage any situation with ease.

Learn how to:
– Remove password protection in Excel
– Edit and manipulate locked Excel files
– Restore protection after making changes
– Use VBA to unlock Excel sheets
– Manage Excel file security without knowing the password
