Preparation
Before attempting to unlock your Excel sheet, ensure you have:
- A legitimate copy of Microsoft Excel installed.

- Patience – this method is quick, but you should still be careful with any file modifications.
Unlocking Your Excel Sheet
Follow these steps to unlock an Excel sheet:
1. Open the Excel Workbook: Start Excel and open the workbook containing the locked sheet.
2. Access the VBA Editor: Press Alt + F11 or go to Developer tab and select Visual Basic to open the VBA editor.
3. Navigate to the Sheet's Code: In the VBA Project window, locate your workbook, expand the folder to see the sheets, and double-click on the locked sheet.
4. Paste the Unlocking Code: Within the sheet's code window, you need to paste the following code:
Sub UnprotectSheet()
Dim i As Integer, j As Integer, k As Integer
Dim l As Integer, m As Integer, n As Integer
Dim strPassword As String
Dim strChar As String
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 n = 32 To 126
strPassword = Chr(i) & Chr(j) & Chr(k) & Chr(l) & Chr(m) & Chr(n)
ActiveSheet.Unprotect Password:=strPassword
If ActiveSheet.ProtectContents = False Then
MsgBox "Password is: " & strPassword
Exit Sub
End If
Next: Next: Next: Next: Next: Next
End Sub
ℹ️ Note: This code attempts to unlock the sheet by trying various combinations of characters.
5. Run the Code: Click Run or press F5 to execute the macro.
💡 Note: The execution might take time as it tests numerous password combinations. You'll see a message box with the password when successful.
