5 Ways to Remove Password Protection in Excel Sheet

If you've ever encountered a password-protected Excel spreadsheet and found yourself in need of accessing the data within, you're not alone. Whether you've forgotten the password or need to bypass the security for legitimate reasons, there are several methods to remove password protection in Excel. Here, we'll explore five effective strategies to help you unlock those guarded sheets:

1. Use Online Decryption Tools

When you’re looking for a quick and often hassle-free solution, online decryption tools can be your first stop. These websites use algorithms to bypass or crack Excel passwords.

• Visit a reputable online Excel password removal tool. Websites like Password-Find or LostMyPass can be quite helpful.
• Upload the encrypted Excel file to their service.
• Wait for the tool to process and decrypt your file. This might take a few minutes depending on the password complexity and file size.
• Download the decrypted Excel file.

🔐 Note: When using online tools, ensure you're using a trusted service since you'll be uploading sensitive data online. Consider the privacy implications.

2. VBA Macros

VBA (Visual Basic for Applications) offers a versatile way to manipulate Excel files, including removing password protection:

• Open your password-protected Excel sheet.
• Press Alt + F11 to open the VBA editor.
• In the left-hand Project pane, find your workbook and double-click ThisWorkbook or the specific sheet where you want to remove protection.
• Copy and paste the following VBA code into the module:

  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 “Password Cracked: ” & 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
  

• Run the macro by pressing F5 or clicking “Run” in the toolbar. The macro will try common password combinations until it finds the one to unprotect your sheet.

⚠️ Note: This method could take some time, especially if the password is complex, and it may not work if macro settings are locked by the password protection.

3. Hex Editor to Modify .xls Files

If you’re dealing with an older version of Excel (.xls), using a hex editor can be another approach:

• Open the .xls file in a hex editor like HxD or UltraEdit.
• Search for the string DPB which indicates the beginning of the password protection information.
• Change this to DBx or another three-letter sequence to overwrite the protection.
• Save the file and attempt to open it in Excel.

🛠 Note: This method is not viable for newer Excel file formats (.xlsx, .xlsm) due to different file structures and encryption methods.

4. Microsoft Office Password Recovery Tool

For Microsoft 365 subscribers, Microsoft provides a password recovery tool:

• Sign in with your Microsoft account and download the tool from the official website.
• Open the software, select “Excel”, and choose your file.
• The tool will attempt to remove or recover the password. This can be especially useful for complex passwords or when the original password is lost.

📝 Note: This tool isn't available for all versions of Office, and you might need to purchase it separately.

5. Reinstall or Repair Excel

Sometimes, a corrupted Excel installation can cause issues with password-protected files:

• Uninstall Excel from your computer.
• Download and install the latest version or repair the existing installation through Control Panel or the Office settings.
• Try opening the protected file again after the installation or repair. This might bypass any issues causing password protection.

Removing password protection from an Excel sheet can be essential for various reasons, from forgotten passwords to needing to access data for legitimate work. Each of these five methods has its own merits:

• Online Decryption Tools: Quick but requires trust in the service's security.
• VBA Macros: Versatile but time-consuming for complex passwords.
• Hex Editor: Requires technical skill, works for .xls only.
• Microsoft Office Tool: Official and reliable, requires subscription.
• Reinstall/Repair: Might solve underlying issues but isn't guaranteed to bypass protection.

In any case, remember that attempting to remove or bypass password protection should only be done with legal and ethical considerations in mind. Unauthorized access to protected data is a serious breach of privacy and security. Always strive for transparency, and where possible, seek permission or legal advice before taking steps to unlock someone else's protected work.

Is it legal to remove password protection from an Excel file?

+

It is not inherently illegal, but it depends on the context. Removing password protection without authorization is an ethical and potentially legal issue. Always ensure you have the right to access the data or permission from the owner before proceeding.

Will using these methods affect the data in the Excel file?

+

Generally, removing password protection does not alter the data itself, but there is always a risk when modifying file structures or using software to bypass security. Ensure you have backups before attempting any of these methods.

Can Excel passwords be recovered if forgotten?

+

If the file is password-protected for editing or viewing, there are tools to attempt recovery or decryption, but there’s no guaranteed method for retrieving the original password. Always make sure to store passwords securely.
