The Challenge of Unprotecting an Excel File without Password
Excel files are often protected with a password to prevent unauthorized access or edits. However, if you forget or lose the password, it can be challenging to access and edit the file. Manually guessing the password can be time-consuming and may not always be successful. Additionally, third-party software that claims to unlock protected Excel files can be risky and potentially harmful to your computer.
Things You Should Prepare for
Before attempting to unprotect an Excel file, there are a few things you should prepare to ensure a smooth and successful process. Firstly, make sure to create a backup of the protected file in case anything goes wrong during the unprotecting process. You will also need to have a copy of Microsoft Excel installed on your computer. Finally, depending on the method you choose, you may need to download and install additional software.
Method 1: Via ZIP
This method works by using a ZIP file to extract the XML file that contains the password information. Here are the steps to follow:
1. Rename the Excel file with a ".zip" file extension.
2. Extract the contents of the ZIP file to a new folder.
3. Navigate to the "xl" folder, then the "worksheets" folder.
4. Open the XML file for the worksheet that is password-protected using a text editor, such as Notepad.
5. Search for the term "sheetProtection" and remove it, including the surrounding "sheetProtection" tags.
6. Save the XML file, then close it and the text editor.
7. Add the edited XML file back to the ZIP file.
8. Rename the ZIP file to its original Excel file name with the ".xlsx" extension.
Pros:
– This method is free and does not require any third-party software.
– It preserves the original formatting and content of the Excel file.
Cons:
– It can be time-consuming, especially if the Excel file contains multiple protected worksheets.
– One mistake while editing the XML file can corrupt the entire Excel file.
Method 2: Using VBA Code
Visual Basic for Applications (VBA) is a programming language used to automate processes in Microsoft Office programs. This method involves using VBA code to bypass the password protection. Here are the steps to follow:
1. Open the Excel file that is password-protected.
2. Press "Alt" and "F11" to open the Microsoft Visual Basic editor.
3. In the editor, navigate to "Insert" and select "Module."
4. 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 "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
Next: Next: Next: Next: Next: Next
Next: Next: Next: Next: Next: Next
End Sub
5. Press "F5" to run the code. It will attempt to guess the password by using a combination of letters and numbers. The usable password(s) will be displayed in a message box.
Pros:
– This method can be quicker than manually guessing the password.
– It does not require any additional software.
Cons:
– It may not always successfully guess the password.
– It can be risky to enable macros and run VBA code from a file from a non-trusted source.
Method 3: Using PassFab for Excel
PassFab for Excel is a third-party software specifically designed for unlocking password-protected Excel files. Here are the steps to follow:
1. Download and install PassFab for Excel on your computer.
2. Open the software and click "Add" to import the password-protected Excel file.
3. Select the attack type: Dictionary, Brute-force, or Brute-force with Mask.
4. Set the attack settings based on your password information.
5. Click "Start" to begin the password recovery process.
6. After the password is recovered, click "Copy" to copy the password to the clipboard.
7. Open the password-protected Excel file and enter the copied password to unprotect it.
Pros:
– This method is specifically designed for unlocking password-protected Excel files.
– It offers different attack types and settings for a customized recovery process.
Cons:
– It requires purchasing and installing third-party software.
– It can be risky to download and install software from a non-trusted source.
Method 4: Using Online Password Unlockers
Several online services claim to unlock password-protected Excel files for free or a fee. While some may work effectively, they can also be risky and potentially harmful to your computer. We do not recommend using online password unlockers for unprotecting Excel files.
Pros:
– Some services may claim to be free.
Cons:
– They can be risky and potentially harmful to your computer.
– There is no guarantee that they will successfully unlock the Excel file.
