5 Proven Methods to Unprotect Excel Sheets Instantly

Let's dive into the world of Excel where protecting and unprotecting sheets is often necessary to control data privacy and integrity. Whether you've forgotten the password or need to make changes to a protected spreadsheet, knowing how to unprotect Excel sheets instantly can be incredibly useful. Here, we'll explore five proven methods to do just that.

Method 1: Using Excel’s Built-In Feature

Excel has an in-built feature for password removal. This can be used if you remember the original password or know someone who does.

• Open the protected Excel workbook.
• Go to Review > Unprotect Sheet or Unprotect Workbook.
• If you know the password, enter it. If not, proceed to other methods.

Method 2: Using VBA Code

Visual Basic for Applications (VBA) can bypass password protection if you have permission to edit the workbook.

Sub PasswordBreaker()
    Dim i As Integer, j As Integer, k As Integer
    Dim l As Integer, m As Integer
    Dim str1 As String
    Dim sheet As Worksheet
    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
            str1 = Chr(i) & Chr(j) & Chr(k) & Chr(l) & Chr(m)
            Set sheet = ActiveSheet
            sheet.Unprotect Password:=str1
            If sheet.ProtectContents = False Then
                MsgBox “One usable password is ” & str1
                Exit Sub
            End If
        Next: Next: Next: Next: Next
    End Sub

Run this VBA script in your Excel to attempt unprotection.

❗ Note: This method is for legal use only with the proper authorization to unprotect the file.

Method 3: Online Unprotection Tools

Several online tools can unprotect Excel sheets without software installation, but use them cautiously due to privacy concerns.

Method 4: Password Recovery Software

Tools like iSunshare Excel Password Recovery, Excel Password Recovery Master, or Stellar Excel Password Recovery can retrieve or remove passwords.

Method 5: Hex Editing

For the tech-savvy, hex editing can alter the Excel file’s metadata to remove protection:

1. Open the Excel file in a hex editor.
2. Search for ‘DPB=’ followed by ‘DDPB=’.
3. Remove the text between these two strings, including the end DPB=.
4. Save the changes, and open the file in Excel.

❗ Note: Modifying files at the hex level can corrupt the file if not done correctly.
