Microsoft Excel is an indispensable tool for data management, analysis, and reporting. However, protecting sensitive information within Excel files with passwords is a common practice. While password protection ensures data security, there are situations where you might need to remove the password, such as when you forget it or when a colleague who set the password is unavailable. Removing an Excel password can be tricky, but with the right methods and tools, it’s entirely achievable. This comprehensive guide will walk you through various methods to remove Excel password protection, covering different scenarios and Excel versions.
Understanding Excel Password Protection
Before diving into the methods, it’s essential to understand the types of password protection Excel offers. Excel provides several levels of password protection:
- Password to Open: This password prevents anyone from opening the Excel file. Without the correct password, the file remains inaccessible.
- Password to Modify: This password allows users to open and view the file, but they cannot make any changes or save the modified version without the correct password. They can only open it as “Read-Only.”
- Password to Protect Sheet: This password protects a specific worksheet within the Excel file, preventing users from editing, deleting, or modifying the sheet’s content, structure, or formatting.
- Password to Protect Workbook Structure: This password prevents users from adding, deleting, hiding, unhiding, or renaming worksheets within the workbook.
- VBA Project Password: This password protects the Visual Basic for Applications (VBA) code within the Excel file, preventing unauthorized access and modification of the code.
The method you use to remove the password will depend on the type of protection applied to the Excel file.
Methods to Remove Excel Password to Open
If you need to remove the “Password to Open,” here are several methods you can try:
Method 1: Using Passware Kit (Third-Party Software)
Passware Kit is a powerful password recovery tool that can remove or recover passwords from various file types, including Excel files. While it’s a commercial software, it offers a trial version that might be sufficient for simpler passwords.

Method 3: Using VBA Code (For Older Excel Versions – Excel 2003 and Earlier)
This method involves using Visual Basic for Applications (VBA) code to attempt to bypass the password protection. This method is primarily effective for older versions of Excel (Excel 2003 and earlier), as newer versions have stronger encryption that makes this method less likely to succeed. Modern excel’s password protection is much more robust.
- Open the Excel File: Open the password-protected Excel file in Excel. If it prompts for a password and you don’t have it, just click “Cancel” to proceed.
- Open the VBA Editor: Press Alt + F11 to open the Visual Basic for Applications (VBA) editor.
- Insert a New Module: In the VBA editor, go to Insert > Module to insert a new module.
- Enter the VBA Code: Copy and paste the following VBA code into the module:
Sub PasswordBreaker() 'Breaks Excel 97-2003 passwords 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 76: 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 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
Important Note: This code is provided for educational purposes only. Using it on files you do not own or have permission to access is unethical and potentially illegal.
- Run the Code: Press F5 to run the VBA code. The code will attempt to brute-force the password.
- Wait for the Code to Complete: The code will iterate through possible password combinations. This process can take a considerable amount of time, depending on the password’s complexity.
- Check for the Password: If the code successfully unprotects the sheet, a message box will appear displaying the password.
- Remove the Password Protection: Once you have the password, go to Review > Unprotect Sheet and enter the password to unprotect the worksheet. Then, save the file without a password.
Limitations of the VBA Code Method:
- Limited Effectiveness: This method is primarily effective for older Excel versions and simple passwords. Newer versions of Excel have stronger encryption, making this method unlikely to succeed.
- Time-Consuming: The brute-force approach can take a very long time, especially for complex passwords.
- Potential Errors: The code might not work in all cases and could potentially cause errors in the Excel file.
Methods to Remove Excel Password to Modify
If the Excel file has a “Password to Modify,” the process is often simpler than removing a “Password to Open.” Here’s how:
Method 1: Opening as Read-Only and Saving a Copy
- Open the Excel File: Open the password-protected Excel file.
- Click “Read Only”: When prompted for the password to modify, click the “Read Only” button. This will open the file in read-only mode.
- Save a Copy: Go to File > Save As and save a copy of the file with a different name or in a different location.
- Close and Reopen the Copy: Close the original file and open the copy you just saved. The copy should no longer be password-protected for modification.
This method works because saving a copy of the file creates a new file without the original password protection settings.
Method 2: Using a Hex Editor (Advanced Users)
This method involves using a hex editor to modify the file’s binary data and remove the password protection. This method is more complex and requires a good understanding of file structures and hexadecimal editing. Incorrectly modifying the file can corrupt it, so proceed with caution and back up the file before attempting this method.
- Download and Install a Hex Editor: Download and install a hex editor on your computer. Popular options include HxD, Frhed, and Hex Workshop.
- Open the Excel File in the Hex Editor: Launch the hex editor and open the password-protected Excel file.
- Search for the Password Protection Flag: Use the hex editor’s search function to find specific hexadecimal values that indicate password protection. The specific values to search for may vary depending on the Excel version, but common search terms include: “50 4B 03 04” and look for surrounding XML structures related to protection. Examine the XML, which will usually be relatively easy to read, for the tag <fileSharing loadReadOnly=”1″…> or similar.
- Modify the Hexadecimal Values: Once you find the relevant hexadecimal values, modify them to disable password protection. This typically involves changing a flag value from “1” to “0” or deleting the password protection related XML structures. Locating and altering the XML is the preferred way to do this.
- Save the Modified File: Save the changes to the Excel file.
- Open the Modified File in Excel: Open the modified Excel file in Excel. It should now be open for editing without requiring a password.
Important Considerations for Using a Hex Editor:
- Backup: Always create a backup of the Excel file before attempting to modify it with a hex editor.
- Complexity: This method is complex and requires advanced technical knowledge.
- Risk of Corruption: Incorrectly modifying the file can corrupt it and make it unusable.
- Excel Version Compatibility: The specific hexadecimal values to search for may vary depending on the Excel version.
Methods to Remove Excel Sheet or Workbook Protection Password
If you need to remove a password that protects a specific sheet or the workbook structure, here are some methods you can use:
Method 1: Using VBA Code (More Effective Than Password to Open)
This VBA code method is generally *more* reliable than the password to open VBA method because of the different level of encryption applied. It can still take a substantial amount of time.
- Open the Excel File: Open the password-protected Excel file.
- Open the VBA Editor: Press Alt + F11 to open the Visual Basic for Applications (VBA) editor.
- Insert a New Module: In the VBA editor, go to Insert > Module to insert a new module.
- Enter the VBA Code: Copy and paste the appropriate VBA code into the module. There are two versions – one to attempt to unprotect *all* sheets, and one to unprotect the entire workbook structure. Choose the version appropriate for your situation. If you are unsure, run both.
Code to Unprotect All Sheets:
Sub UnprotectAllSheets() Dim ws As Worksheet On Error Resume Next For Each ws In ActiveWorkbook.Worksheets ws.Unprotect Password:="" Next ws MsgBox "All sheets unprotected (if they had a simple password)." End Sub
Code to Unprotect Workbook Structure:
Sub UnprotectWorkbook() On Error Resume Next ActiveWorkbook.Unprotect Password:="" MsgBox "Workbook structure unprotected (if it had a simple password)." End Sub
Important Note: This code is provided for educational purposes only. Using it on files you do not own or have permission to access is unethical and potentially illegal.
- Run the Code: Press F5 to run the VBA code.
