Using VBA Code to Unprotect Sheet

Step 1: Open the Excel file containing the protected sheet you wish to unprotect.

Step 2: Press Alt + F11 on your keyboard to open the Visual Basic for Applications (VBA) editor.

Step 3: In the VBA editor, locate the left pane labeled Project-VBAProject. Expand the Microsoft Excel Objects folder, right-click on the protected sheet, select Insert, and then choose Module.

Step 4: In the new Module window that appears, paste the following VBA 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 = 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 "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
    End Sub

Step 5: Press F5 or click on the Run button in the toolbar to execute the code. The macro will attempt to unprotect the sheet. This process may take some time depending on your system.

Once the macro has finished running, your sheet should be unprotected and editable.

Using Zip File Format Trick for Sheet

Step 1: Navigate to the Control Panel on your computer and select File Explorer Options.

Step 4: Open the renamed zip file. Navigate to the xl folder to access the workbook's contents.

Step 5: Inside the xl folder, open the worksheets directory. You'll see a list of XML files representing each sheet in the workbook.

Step 6: Identify the XML file corresponding to the protected sheet. Right-click on this file, hover over Open with, and select Notepad.

Step 10: Rename the new zip file, changing the extension from .zip back to .xlsx. Confirm the change if prompted.

You can now open the Excel file, and the previously protected sheet will be unprotected and editable.
