5 Ways to Unprotect Excel Sheet 2010 Easily

Microsoft Excel 2010 is widely recognized as a powerful tool for managing and analyzing data, but one of its lesser-known features is the ability to protect spreadsheets from unauthorized edits. However, there are legitimate scenarios where accessing or modifying a protected sheet is necessary. In this guide, we'll explore five effective methods to unprotect an Excel sheet 2010 that has been locked with a password.

Method 1: Using the PassFab for Excel

PassFab for Excel is a reputable software designed specifically to recover passwords from Excel files, including Excel 2010. Here’s how you can use it to unprotect your Excel sheet:

• Download and Install: Begin by downloading the PassFab for Excel from their official website and install it on your computer.
• Open the Program: Launch the PassFab for Excel application.
• Load the Excel File: Navigate to your protected Excel file by clicking on ‘Add’, and select the file.
• Start Recovery: Choose ‘Recover Excel Open Password’ if you need to open the file or ‘Remove Excel Restriction Password’ to unprotect the sheet, then click on ‘Start’.
• Retrieve Password or Unprotect Sheet: Once the process is complete, you’ll either recover the password or unprotect the sheet directly.

Method 2: VBA Code to Bypass Protection

If you have access to the Excel file and can run Visual Basic for Applications (VBA) macros, here’s how you can unprotect your worksheet:

• Press Alt + F11 to open the VBA editor.
• In the Project Explorer, right-click on the desired sheet name, and choose ‘Insert’ then ‘Module’.
• Copy and paste the following code into the module:

Sub UnprotectSheet()
Dim i As Integer, j As Integer, k As Integer
Dim l As Integer, m As Integer, n As Integer
Dim char1 As Integer, char2 As Integer
Dim pass As String

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 = 32 To 126

pass = Chr(i) & Chr(j) & Chr(k) & Chr(l) & Chr(m) & Chr(i1)

On Error Resume Next
If ActiveSheet.Unprotect(pass) Then
    MsgBox “Password is ” & pass
    Exit Sub
End If
Next: Next: Next: Next: Next: Next
End Sub

• Run this Macro: Close the VBA editor, go back to Excel, and press Alt + F8 to run the macro. Select ‘UnprotectSheet’ and click ‘Run’.

🎯 Note: This VBA method can be time-consuming as it brute-forces every combination. Ensure your file does not contain macros that might conflict with this script.

Method 3: Online Unprotect Excel Services

There are various online services that offer password recovery or sheet protection removal, although caution is necessary when uploading sensitive data:

• Select a Reputable Service: Choose a service known for its security like Excel Unlocker Online or LostMyPass.
• Upload Your File: Follow the service provider’s steps to upload your Excel file.
• Unlock the Sheet: Depending on the service, you might receive the password or an unlocked version of your sheet.

Method 4: Editing the Excel File Structure

This method involves altering the file structure, which is more advanced and might void the integrity of the file:

• Save as XML: Open your Excel file in Excel 2010 and save it as XML Spreadsheet 2003.
• Open with Text Editor: Open the XML file in Notepad or any text editor.
• Locate the Protection Tag: Search for the tag and change the attribute password=“” to password=“” algorithm=“” saltValue=“” spinCount=“”. Essentially, you’re nullifying the protection.
• Save and Open: Save the XML, close it, and then open it again in Excel, ensuring the sheet is unprotected.

💡 Note: This method requires basic knowledge of XML file structures and can lead to data corruption if not done correctly.

Method 5: Using ZIP Tool to Edit Excel File

Excel 2010 files are essentially zip archives containing XML files:

• Rename the File: Change the .xlsx extension to .zip.
• Extract the Archive: Open the .zip file to access its contents.
• Find and Edit Workbook.xml: Locate the file named Workbook.xml inside xl/workbook.xml. Edit this file to remove or alter the protection attributes as described in Method 4.
• Repackage and Rename: Zip all files back into an archive, rename the extension back to .xlsx, and open with Excel.

This recap provides an overview of five methods to unprotect an Excel sheet in Microsoft Excel 2010. Each method has its place depending on your access level to the file, the urgency, and the technical skills you possess. Remember that if the data within the Excel file is critical, proceed with caution, especially when using methods involving external tools or editing file structures. For routine access, using PassFab for Excel or running a VBA macro might be the most straightforward and less risky options. However, for those with technical inclination, altering the file structure or using ZIP tools offers a creative but more complex approach.
