Unlock Hidden Protected Excel Sheets Easily

If you've ever stumbled upon an Excel workbook where you can only peek through the cells without the freedom to modify them, you're not alone. Excel sheets often come protected to ensure data integrity or to lock down formulas from being altered by users without proper authorization. However, there are legitimate reasons why you might need to unlock these protected sheets - maybe you're a new employee who inherited a project or a freelancer needing to make critical adjustments. Whatever your situation, today's tutorial will guide you through the process of unlocking hidden protected Excel sheets with ease.

Why Do Excel Sheets Get Protected?

Excel spreadsheets can be locked for several reasons:

• Security: To safeguard against unauthorized changes or data breaches.
• Data Integrity: Protecting the accuracy of data by preventing accidental or intentional edits.
• Template Preservation: Ensuring that a template’s structure and formulas are not tampered with.

Understanding Excel Protection

Excel protection isn’t a single lock; it consists of different layers:

• Worksheet Protection: Stops editing within a sheet.
• Workbook Structure Protection: Prevents adding, moving, renaming, or deleting sheets.
• VBA Protection: Secures VBA modules and scripts from modification.

Understanding these layers can help us determine the best method to unlock a sheet.

Steps to Unlock Protected Excel Sheets

Here’s how to go about unlocking your Excel sheets:

1. Using the Password

   
   

   If you or someone in your team knows the password:

   • Open the workbook.
   • Go to Review > Unprotect Sheet or Unprotect Workbook and enter the password.

2. Removing Protection Without the Password

   
   

   In cases where the password is unknown or lost:

   1. Open the protected Excel file.
   2. Press Alt + F11 to open the Visual Basic Editor.
   3. Insert a new module with Insert > Module.
   4. Copy-paste the following code:

   
   Sub PasswordBreaker()
       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 = 32 To 126: For m = 32 To 126: For i1 = 32 To 126
               For i2 = 32 To 126: For i3 = 32 To 126: For i4 = 32 To 126
                   For i5 = 32 To 126: For i6 = 32 To 126: 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 “One usable password is ” & Chr(i) & Chr(j) & Chr(k) & _
                                  Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & _
                                  Chr(i4) & Chr(i5) & Chr(i6) & Chr(n)
                           Exit Sub
                       End If
                   Next: Next: Next: Next: Next: Next
               Next: Next: Next: Next: Next: Next
           Next: Next: Next
       Password = InputBox(“Password not found. Enter your custom password”)
       ActiveSheet.Unprotect Password
   End Sub
               

   5. Run the macro by pressing F5 or Ctrl + G.
   6. The macro will try to crack the password by brute force. If successful, the sheet will be unprotected, and a message will show the password.

🔑 Note: Be cautious when using this method, as it can be time-consuming, and the ethical implications of bypassing someone's protection should be considered.

When you unlock an Excel sheet, you are granted the ability to edit it, but this comes with a responsibility:

• Ensure that you have the right to modify the document.
• Be mindful of any confidential information contained within.
