There are several open-source tools on GitHub designed to remove password protection from Excel files. These tools typically work by modifying the internal XML structure of modern .xlsx or .xlsm files to strip out "Sheet Protection" or "Workbook Protection" tags. Popular GitHub Tools

Excel Unlocker (ajott): A portable C# application that removes sheet and VBA protection without requiring installation.

Excel-Worksheet-Password-Remover (aziascreations): A tool that simplifies editing XML files in your browser to remove worksheet passwords.

Unprotexcel (azmke): A lightweight Java-based tool with a user-friendly interface for Windows, Mac, and Linux.

Excelled-web (AlecBlance): A client-side web app that allows you to upload a file to remove protections entirely in your browser. General Guide to Using a GitHub Excel Password Remover

While each repository has specific instructions, most follow this general workflow:

Backup Your File: Always create a copy of your protected Excel file before using any tool to prevent data loss. Download the Tool:

For executables (like Excel Unlocker), go to the "Releases" section of the repository and download the latest .exe file. Excel Password Remover Github

For scripts (Python/Bash), clone the repository using git clone [repository-url] or download the ZIP. Run the Removal Process:

GUI Tools: Open the application, select your Excel file, and click "Unlock" or "Remove Protection".

Command Line Scripts: Use a terminal to navigate to the script folder and run the command (e.g., python script_name.py yourfile.xlsx).

Save the New File: The tool will usually generate a new version of your file (often with a suffix like _unlocked.xlsx) that is no longer protected. Limitations to Consider

The intersection of Microsoft Excel’s security and the open-source community on GitHub has created a specialized niche for "Password Removers." These tools are frequently sought by users who have lost access to critical spreadsheets or by security researchers testing the robustness of office document encryption.  The Role of GitHub in Excel Security 

GitHub serves as a central repository for various scripts and applications designed to bypass or remove Excel protections. These projects typically fall into two categories: 

VBA Macro Removers: Scripts that strip the password protection from the Visual Basic for Applications (VBA) project structure within a workbook. MIT License – free for personal and educational use

Sheet/Workbook Unprotectors: Tools that modify the XML structure of modern .xlsx or .xlsm files to remove "Read-Only" or sheet-level protection without needing the original password.  Popular Methodologies 

Most tools found on GitHub, such as those within the Excel Password Remover search results, utilize one of the following methods: 

XML Modification: Since modern Excel files are essentially zipped XML files, many Python or PowerShell scripts on GitHub unzip the file, find the sheetProtection or workbookProtection tags, and delete them.

Hex Editing: For older .xls (97-2003) formats, some tools use hex editing to change specific bytes that signal to Excel that a password is required.

Brute Force/Dictionary Attacks: While rarer for high-level file encryption (which is computationally expensive), some repositories provide wrappers for tools like John the Ripper or Hashcat to crack actual file-open passwords.  Ethical and Security Considerations 

Using password removal tools from GitHub comes with significant caveats: 

Security Risks: Running arbitrary code or scripts from unverified repositories can expose a system to malware or data exfiltration.

Data Integrity: Improperly modifying the XML structure of a spreadsheet can lead to file corruption. There are several open-source tools on GitHub designed

Legal Compliance: These tools should only be used on files for which the user has legal ownership or explicit permission to access.  Conclusion 

GitHub remains a vital resource for recovery and research, offering transparent, community-vetted alternatives to expensive proprietary software. However, the move toward stronger AES-256 encryption in recent Microsoft Office versions means that simple XML "stripping" is increasingly limited to removing editing restrictions rather than cracking complex "open" passwords. 

The typical usage is:

python remove_password.py locked_file.xlsx output_file.xlsx

A search for "Excel Password Remover" on GitHub reveals several popular methodologies. Here is a breakdown of the most effective open-source solutions available.

This prevents users from saving changes or editing the sheet. It is notoriously weak.
