Unlock and Delete Protected Excel Sheets Easily

Excel worksheets often contain sensitive data, making them protected to prevent unauthorized changes. But what if you need to unlock or even delete such protected sheets? Whether for recovery purposes, updates, or to redistribute documents, this comprehensive guide will detail a variety of methods to help you unlock and delete these sheets with ease.

Understanding Excel Protection

Excel offers multiple layers of protection:

• File Protection: Passcode at the file level.
• Sheet Protection: Limits the ability to edit within sheets.
• Workbook Protection: Prevents structural modifications like adding or deleting sheets.

Below are the various methods to bypass or remove these protection barriers.

Using a Password

The most direct method is entering the password to unprotect a sheet:

1. Select the protected sheet you wish to unlock.
2. Go to the ‘Review’ tab.
3. Click on ‘Unprotect Sheet.’
4. Enter the password provided.

This method is foolproof if you have the password. However, if you don’t, other techniques are required.

Forgotten Passwords: VBA Method

If the password is lost, VBA can help:

1. Open your Excel file.
2. Press Alt + F11 to open the VBA Editor.
3. In the Project Explorer, right-click on the sheet and select ‘View Code.’
4. Enter 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
   Dim num1 As String, num2 As String, num3 As String
   Dim num4 As String, num5 As String, num6 As String

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 = 48 To 57
   For i2 = 48 To 57: For i3 = 48 To 57: For i4 = 48 To 57
   For i5 = 48 To 57: For i6 = 48 To 57
       num1 = Chr(i) & Chr(j) & Chr(k) & Chr(l) & Chr(m)
       num2 = Chr(i1) & Chr(i2) & Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6)
       If Sheet1.Unprotect(num1 & num2) = False Then
           MsgBox “Password Found! It’s ” & num1 & num2
           Exit Sub
       End If
   Next: Next: Next: Next: Next: Next
   Next: Next: Next: Next: Next: Next
End Sub

🔑 Note: Remember, using this method ethically is essential.
