5 Ways to Unprotect Excel Sheet in Office 2007

Microsoft Excel is a powerful tool for organizing and analyzing data, but sometimes the protections we put in place can hinder our own progress. If you've forgotten a password or inherited an Excel sheet from someone else without access, it can be frustrating. Here, we explore five methods to unprotect an Excel sheet in Microsoft Office 2007, ensuring you regain control over your data.

Method 1: Using the VBA Code

Visual Basic for Applications (VBA) is an event-driven programming language built into Microsoft Office applications like Excel. Here’s how to use VBA to unprotect your sheet:

1. Press Alt + F11 to open the VBA Editor.
2. Click Insert and then Module.
3. Copy and 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 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
           With Sheets(1)
               If Chr(i) & Chr(j) & Chr(k) & Chr(l) & Chr(m) & Chr(i1) & Chr(i2) & Chr(i3) & Chr(i4) & Chr(i5) & Chr(i6) & Chr(n) = .ProtectContents = True Then
                   .Unprotect Password:=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 .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
               End If
           End With
       Next: Next: Next: Next: Next: Next
       Next: Next: Next: Next: Next: Next
   End Sub
   
   

4. Press F5 to run the macro.

⚠️ Note: This method will attempt to break any password set for sheet protection, which might take some time for complex passwords.

Method 2: Using External Tools

Several third-party software tools are available to help unprotect Excel sheets:

• Excel Password Recovery Tool: Programs like PassFab for Excel or iSeePassword Excel Password Recovery can break or recover passwords.
• VBA Codes: Online forums often provide updated VBA scripts for password removal.

After downloading and installing one of these tools:

1. Open the software and import your Excel file.
2. Select the sheet to unprotect.
3. Initiate the password recovery process.

Method 3: Using Zip File Trick

This unconventional method works because older versions of Excel used zip compression for their file format:

1. Change the .xlsx file extension to .zip.
2. Extract the zip file.
3. Navigate to the xl folder, then to worksheets.
4. Open each .xml file corresponding to your sheets with a text editor.
5. Look for <sheetProtection/> and either remove or edit this tag to disable protection.
6. Save changes, re-zip, and rename back to .xlsx.

Method 4: Hex Editor Method

If you’re comfortable with binary editing, you can use a Hex Editor to modify the file:

1. Backup your Excel file.
2. Open the .xls file in a Hex Editor.
3. Search for “DPB=” or “DBP=”, which indicates password protection.
4. Remove or modify these bytes.
5. Save the file and check if the protection is lifted.

⚠️ Note: This method can corrupt your file if done incorrectly. Proceed with caution.

Method 5: Requesting Access

If you legally have the right to the data but don’t have the password:

• Ask the Owner: Request the password from the file’s creator.
• Office Admin: If part of an enterprise, ask IT or system admin for assistance.

While these methods can help you regain access to protected Excel sheets, always ensure you have the right to access the data. Unprotecting sheets without permission can lead to ethical and legal issues. In the end, using these techniques responsibly helps maintain the integrity of your work environment.

If you’ve forgotten a password or need to access protected sheets often, consider implementing better password management practices or exploring Excel features like Document Recovery** or Shared Workbooks for better collaboration without compromising security.
