5 Proven Ways to Unlock Password-Protected Excel Sheets

Securing an Excel spreadsheet with a password is a common practice to protect sensitive data. However, there might be legitimate reasons for needing to access such documents, like lost passwords, inherited workbooks, or recovering information from an old drive. This blog post outlines five proven methods to unlock password-protected Excel sheets, offering both technical and non-technical approaches for accessing secured data.

Method 1: Contact the Owner

Before delving into technical methods, it’s essential to consider ethical and straightforward options:

• If you know who set the password, simply request access.
• Explain why you need access and ensure to maintain the document’s confidentiality.

Method 2: Using VBA Macros

VBA (Visual Basic for Applications) can be employed to unlock an Excel file:

1. Open a blank Excel sheet.
2. Press Alt + F11 to open the VBA editor.
3. Insert a new module via Insert > Module.
4. Paste the following code:

Sub PasswordBreaker()
Dim Password As String
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
                    Password = Chr(i) & Chr(j) & Chr(k) & Chr(L) & Chr(m)
                    If Password = ThisWorkbook.Password Then
                        MsgBox (“Password is ” & Password)
                        Exit Sub
                    End If
                Next m
            Next L
        Next k
    Next j
Next i
Password = “Nothing Found!”
End Sub

5. Close the VBA editor and run the macro with Developer > Macros > PasswordBreaker > Run.

This macro attempts to guess the password through an exhaustive method. However, this approach is limited to short passwords.

💡 Note: Macros can be a significant security risk if obtained from untrusted sources.

Method 3: Manual Password Guessing

Sometimes, you might know or guess common passwords or patterns:

• Common names, dates of birth, or simple sequences.
• Try common variations of the sheet owner’s name, like first name, last name, or initials.

This method is only practical if you have some knowledge about the person who secured the document.

Method 4: Excel File Protection Tools

There are third-party software solutions designed to bypass Excel password protection:

• Advanced Excel Password Recovery by Elcomsoft.
• Excel Password Recovery by PassFab.
• AsthaSoft Excel Password Recovery.

These tools use advanced algorithms to crack passwords, but be aware:

• Some might not work for newer versions of Excel due to enhanced encryption.
• Cost might be a factor, especially for premium software.

🔒 Note: Ensure the software is reputable and purchased from the original vendor to avoid malware risks.

Method 5: Encryption-Defeating Tactics

If the password protection is simply for editing rather than viewing, here are some workarounds:

1. Copy and Paste: Open the file, copy the content, and paste it into a new sheet.
2. File Conversion: Save the file in an unprotected format like CSV and then re-import it into Excel.
3. Change File Type: Rename the .xlsx extension to .zip, extract the XML files, and modify them to remove the password protection.

🔓 Note: Be cautious when changing file extensions, as it can corrupt the file if not done correctly.

In summary, unlocking a password-protected Excel sheet can be approached in various ways, from contacting the owner, using VBA macros, manual guessing, employing recovery software, to clever file manipulation. Each method has its own set of considerations regarding ethics, efficacy, and the potential for security risks. Understanding the protection level, the urgency of access, and the ethical implications will help you choose the most suitable method.

Is it legal to unlock an Excel sheet that I don’t own?

+

Generally, it’s illegal to bypass password protection without the owner’s consent, as it’s considered unauthorized access. Always ensure you have the owner’s permission or a legal right to access the document.

Can all Excel password protection be unlocked?

+

Not all Excel password protections can be unlocked, especially with newer versions of Excel that use stronger encryption. The success rate often depends on the method used and the complexity of the password.

What if I forget the password to my own Excel sheet?

+

If you’ve forgotten your own Excel sheet’s password, methods like VBA macros or password recovery software can be useful, but remember, always maintain secure backups of your work and passwords.
