Method 2: Removing password protection with VBA code

If you would prefer to use an offline method to remove password protection from your Excel file, then unlocking it with VBA code is an excellent option. VBA code is a powerful tool used to automate Excel tasks, and it can also be used to unlock protected files. Here are the steps to follow:

1. Open Excel and press Alt + F11 to open the VBA editor.
2. Right-click the blank area to the left of the Excel VBA editor.
3. Click Insert and then Module.
4. Enter the following code into the module:

'Breaks worksheet password protection.
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) & i1 & i2 & i3 & i4 & i5 & i6 & Chr(n)
If ActiveSheet.ProtectContents = False Then
MsgBox "One usable password is " & Chr(i) & Chr(j) & _
Chr(k) & Chr(l) & Chr(m) & i1 & i2 & i3 & i4 & i5 & i6 & _

Method 3: Unlock Excel files using an XML editor

If neither of the above methods work for your particular Excel file, you may be able to unlock it using an XML editor. This method involves manually editing the XML file used to create the Excel document and then removing the password protection. Here are the steps to follow:

1. Change the file extension to .zip instead of .xlsx
2. Unzip the file using an archiving software
3. Look for a folder called ‘xl’
4. Navigate to ‘xl\worksheets’
5. Find the XML file that corresponds to the protected sheet
6. Edit the XML file using a text editor and remove the protected sheet elements
7. Save the XML file and close the editor
8. Zip the folder again and change the file extension back to .xlsx
9. Open the file in Excel and access the protected sheet
