5 Ways to Unlock Excel Password-Protected Sheets

Many Excel users encounter the frustration of being locked out of password-protected spreadsheets at some point. Whether it's for accessing an old file, working on a project where the password has been forgotten, or simply exploring the contents of a sheet without the intent of harm, there are legitimate reasons to unlock Excel password-protected sheets. In this detailed guide, we'll walk through 5 ways to unlock an Excel password-protected sheet without software or online tools.

1. Using VBA Code

Visual Basic for Applications (VBA) offers a programmatic way to remove Excel file password protection:

• Open the Excel file that has the protected worksheet.
• Press Alt + F11 to open the VBA editor.
• Click on 'Insert', then 'Module' to insert a new module.
• Copy and paste the following VBA code into the module window:

  
  Sub PasswordBreaker()
      'This code is for educational purposes only. Always respect intellectual property and data security.
      Dim i As Integer, j As Integer, k As Integer
      Dim l As Integer, m As Integer
      Dim str1 As String, str2 As String, str3 As String, str4 As String
      Dim str5 As String, str6 As String, str7 As String, str8 As String
  
      On Error Resume Next
  
      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
                  str1 = Chr(i) & Chr(j) & Chr(k) & Chr(l)
                  str2 = Chr(i) & Chr(j) & Chr(k) & Chr(l) & Chr(m)
                  str3 = Chr(j) & Chr(k) & Chr(l) & Chr(i) & Chr(m)
                  str4 = Chr(j) & Chr(k) & Chr(l) & Chr(i)
                  str5 = Chr(k) & Chr(l) & Chr(i) & Chr(j) & Chr(m)
                  str6 = Chr(k) & Chr(l) & Chr(i) & Chr(j)
                  str7 = Chr(l) & Chr(i) & Chr(j) & Chr(k) & Chr(m)
                  str8 = Chr(l) & Chr(i) & Chr(j) & Chr(k)
  
                  With Sheets(1)
                      .Unprotect str1
                      .Unprotect str2
                      .Unprotect str3
                      .Unprotect str4
                      .Unprotect str5
                      .Unprotect str6
                      .Unprotect str7
                      .Unprotect str8
                  End With
  
                  If Sheets(1).ProtectContents = False Then
                      MsgBox "Password is " & str1 & str2 & str3 & str4 & str5 & str6 & str7 & str8
                      Exit Sub
                  End If
              Next: Next: Next: Next: Next
  
      MsgBox "Password not found."
  End Sub
  
  

• Run the macro by pressing F5 or clicking the 'Run' button.
• The password will be displayed in a message box if it's found.

⚠️ Note: This method should only be used ethically and for files you have legal access to. Unauthorized access to protected data is illegal.

2. Using Saved Password History

Sometimes, Excel or the operating system saves the passwords for recently opened password-protected spreadsheets:

• Re-open the Excel file, and if you've recently used the same password for another file, check the auto-complete or recent password entries:
• Windows users can check the Credential Manager in the Control Panel under 'User Accounts' for stored credentials.
• On a Mac, passwords saved in Keychain Access might help.

3. Excel Options

Excel itself offers an option to remember passwords:

• Open the workbook and go to the 'File' menu.
• Select 'Options' (in older versions, it might be 'Excel Options').
• Go to the 'Save' tab.
• Check the box for "Unprotect Excel Workbook and Sheets when workbook is opened."
• Reopen the file; if you've previously entered the password, Excel might remember it.

🔍 Note: This does not remove the password permanently, just unlocks the sheet during the session.

4. File Unprotect Software

While not using online tools, software specifically designed for unprotecting Excel sheets can be downloaded:

• Software like SysTools Excel Unprotect or Excel Password Unlocker can be used. Ensure you download from reputable sources to avoid malware.
• These tools often work by brute force, dictionary attacks, or by exploiting known vulnerabilities.
• Use such tools with ethical consideration and for files you have the legal right to access.

5. Reset Protection at Workbook Level

Sometimes the protection is at the workbook level, not the individual sheets:

• Open the Excel file.
• Go to the 'Review' tab.
• Click on 'Unprotect Workbook' or 'Unprotect Sheet.'
• If a password is required, try to recover it as in the above methods or consult the original author.
• If no password is set, the protection might be removed outright.

In Closing, unlocking a password-protected Excel sheet should be done with integrity. It's not only about accessing the data but also respecting the privacy and security measures that were initially set. Here are some final points to keep in mind:

• Always back up your Excel files before attempting to unlock them.
• Understand that legal and ethical considerations must be at the forefront when dealing with protected documents.
• Remember that protection is often set for a reason, whether to prevent accidental edits or secure sensitive information.

The methods described aim to help you regain access to files when the password is genuinely lost, but they must be used appropriately and within legal bounds. Securely managing and remembering passwords is still the best practice for maintaining access to your important spreadsheets.

Is it legal to unlock password-protected Excel sheets?

+

Unlocking password-protected Excel sheets is generally legal only if you have legal rights to access the data. Unauthorized access, even if technically possible, can be illegal.

Can unlocking an Excel sheet remove the password?

+

The methods described can unlock the sheet but might not remove the password. To permanently remove password protection, you would need to save or resave the file after unlocking.

What should I do if none of these methods work?

+

If you legitimately need access and none of these methods work, you might need to:

• Contact the file’s owner or creator for the password.
• Look for alternative sources of the data or any backups.
• Consult with IT support or consider professional recovery services if the data is critical.
