Microsoft Excel is one of the most versatile tools for managing data, but the various password protection features it offers can sometimes become obstacles, especially when passwords are forgotten or files are inherited without proper access. Understanding the types of passwords applied in Excel and how to address them is crucial to regaining access without compromising the integrity of your files.
In this guide, we’ll explore the methods for removing all six types of Excel passwords: file open, file modify, workbook protection, worksheet protection, allow edit ranges, and VBA project passwords.
Understanding Excel Password Types
Excel offers different layers of password protection, each designed for a specific purpose. File open passwords are the most robust and prevent unauthorized users from opening the file entirely. These passwords use strong encryption algorithms, making them difficult to bypass without specialized tools. File modify passwords, on the other hand, allow users to open the file in read-only mode but require a password to edit or save changes.
Workbook protection passwords restrict structural modifications, such as adding, deleting, or rearranging worksheets. Similarly, worksheet protection passwords control cell-level permissions, safeguarding specific ranges from being edited or formatted. Allow edit ranges passwords limit who can edit predefined sections of a sheet. And of course, VBA project passwords lock access to the Visual Basic for Applications editor, securing macros and other automation scripts within the workbook.
Each type of password serves a unique purpose, but removing them varies in complexity and legality. The following sections detail the removal processes for each type of protection.
File Open Passwords
Among all Excel password protections, file open passwords are the most secure due to their use of advanced encryption, such as AES-256. Recovering or removing these passwords requires external assistance in most cases, as Excel itself does not offer a workaround.
To remove a file open password, third-party tools such as PassFab for Excel, iMyFone Passper, or Elcomsoft Advanced Office Password Recovery are often used. These tools employ techniques like brute-force attacks, mask attacks, or dictionary attacks, to recover the password. The effectiveness of these tools depends on the complexity and length of the password. Using such tools typically involves selecting the encrypted file, choosing the recovery method, and letting the tool attempt various combinations until the password is identified. While effective, this method can be time-consuming and is contingent on the encryption level used in the file.
File Modify Passwords
File modify passwords are less secure compared to file open passwords. These passwords prompt users to open the file in read-only mode if the password is unknown, allowing basic access but restricting edits. Removing this restriction is relatively straightforward.
One simple method is to open the file in read-only mode and save it as a new file. When saving, choose a different file name or location. This process removes the modify password entirely. Unlike file open passwords, this method does not require external tools and works with most Excel versions.
Workbook Protection Passwords
Workbook protection passwords prevent users from making structural changes to the workbook, such as adding or deleting sheets. Removing this type of protection can be achieved using manual XML editing or VBA macros.
For manual XML editing, begin by changing the file extension from .xlsx to .zip. Excel files in modern formats are essentially compressed archives containing XML files. Extract the contents of the file using a compression tool like WinRAR or 7-Zip. Locate the workbook.xml file within the xl folder and open it with a text editor such as Notepad++. Search for <workbookProtection> tags, which define the password attributes, and delete these tags entirely. Once the edits are complete, repackage the files into a compressed .zip archive and rename the extension back to .xlsx. When you open the modified file, the workbook protection will be removed.
Alternatively, VBA macros can be used to remove workbook protection. Open a new Excel workbook and launch the VBA editor by pressing Alt + F11. Insert a new module and paste a VBA script designed to unprotect the workbook. Running the script will remove the protection and restore full access.
Worksheet Protection Passwords
Worksheet protection passwords restrict access to specific cells or ranges within a sheet. Similar to workbook protection passwords, these can also be removed through XML editing or VBA macros.
For XML editing, follow the same steps as above to access the XML files within the .zip archive. In this case, look for sheetX.xml files (where X corresponds to the sheet number) within the xl/worksheets folder. Open these files in a text editor and locate the <sheetProtection> tags. Delete these tags or remove the attributes specifying the password. Save the changes, repackage the file, and rename the extension to .xlsx.
Using VBA macros provides another effective solution. Open the workbook and launch the VBA editor. Insert a module and paste VBA code that loops through all the sheets in the workbook, unprotecting them one by one. When you run this script, all protected worksheets will be unlocked.
Allow Edit Ranges Passwords
Allow edit range passwords to provide granular control over specific ranges in a worksheet. These passwords are used in conjunction with worksheet protection to create editable zones for certain users. Removing them involves a similar process as removing worksheet protection passwords.
To remove these passwords manually, access the XML files by converting the .xlsx file to a .zip archive. Look for protectedRanges tags in the sheetX.xml files and delete the password attributes. After saving the changes, repackage the file and revert the extension to .xlsx.
VBA macros can also be used to unprotect editable ranges. However, this process is less common as manually editing the XML files is typically quicker and equally effective.
VBA Project Passwords
VBA project passwords secure the Visual Basic editor, preventing unauthorized access to macros and scripts. Cracking these passwords involves modifying the binary content of the file or using specialized tools.
One manual method is to change the file extension of the workbook to .bin and open it in a hex editor like HxD. Locate the DPB= string in the file and replace it with DPx=. Save the file and revert the extension to .xlsm. When you open the workbook in Excel, the VBA project will prompt for a password. Enter “password” to unlock it. While effective, this method requires familiarity with hexadecimal editing to avoid corrupting the file.
Third-party tools like VBA Password Bypasser offer a more user-friendly approach. These tools are specifically designed to bypass VBA project passwords and are ideal for users who prefer automated solutions.

Precautions and Considerations
Before attempting to remove any password, it is essential to back up the original file. Password removal can occasionally corrupt the file, especially if XML editing is done improperly. Additionally, it is important to consider the ethical and legal implications. Password removal should only be attempted on files that you own or have explicit permission to access. Unauthorized cracking of passwords can violate laws or organizational policies.
Compatibility is another factor to consider. Certain methods may not work on newer versions of Excel due to enhanced security measures. For example, file open passwords in newer Excel versions use stronger encryption, making them virtually impossible to bypass without specialized software.
Conclusion
Excel password protection is a critical feature for safeguarding sensitive data, but it can also become a barrier when passwords are forgotten or misplaced. Understanding the specific type of protection applied to a file is key to determining the most appropriate removal method. From straightforward solutions like saving a file copy to advanced techniques such as XML editing and using VBA macros, there are multiple approaches to address the issue. However, file-open passwords may require third-party tools due to their robust encryption.
By following the methods outlined in this guide, you can regain access to your Excel document while maintaining data integrity. Always act responsibly, ensuring you have the right to modify the files in question and back up your data before making changes. With these precautions in place, you can navigate Excel’s password protections with confidence and efficiency.
