PassWiper for Excel is a third-party software utility built to recover forgotten “Passwords to Open” or directly remove structural editing restrictions from Microsoft Excel files. It supports .xls, .xlsx, and other spreadsheet formats across all versions from Excel 2003 up to modern Office 365 files.
Below is a complete overview and step-by-step tutorial on how the software operates. Key Capabilities of PassWiper
Bypasses Sheet/Workbook Restrictions: Instantly deletes passwords that prevent you from editing cells, changing structures, or printing.
Recovers Opening Passwords: Cracks complex encryption keys required to open locked spreadsheets.
Preserves Original Data: Operates safely on your local machine without altering or corrupting the formulas and data inside the file. Full Tutorial: How to Use PassWiper for Excel
Part 1: Removing Editing Restrictions (Read-Only/Sheet Lock)
If you can open the Excel file but cannot modify its content, delete sheets, or format cells, follow these steps:
Launch the Software: Open PassWiper for Excel on your computer.
Select Mode: Click the Remove Restrictions option on the main dashboard.
Import File: Drag and drop your locked Excel file into the software pane, or click the add button to browse your folders.
Remove Protection: Click the Remove button. The software will process the document in a matter of seconds.
Save the File: Click Save to export a completely unlocked copy of your spreadsheet to your desktop. Part 2: Recovering a Forgotten “Password to Open”
If the Excel spreadsheet is completely encrypted and asks for a password just to view it, you will need to utilize the recovery module:
Select Mode: Launch the program and choose Recover Passwords.
Upload Document: Load your password-protected Excel file into the user interface.
Select an Attack Mode: Choose one of the three decryption strategies depending on what you remember about the password:
Dictionary Attack: The software tests millions of common, predefined phrases and passwords. You can also upload your own text file dictionary.
Combination Attack: You define specific parameters (e.g., you remember it starts with a capital “J” and contains numbers). The program randomizes only those selected criteria to speed up recovery times.
Brute-Force Attack: The program attempts every single character combination possible. This takes the longest time and relies heavily on your computer’s processing power.
Initiate Decryption: Click Recover. The software leverages your computer’s CPU and GPU acceleration to run through combinations.
Retrieve Password: Once found, the valid password will display clearly on your screen. Copy it to open your original file natively in Excel. Free Alternative (No Software Needed)
If your file is only locked for editing (Sheet Protection) and you do not want to purchase third-party software, you can manually unlock it using a standard zip extraction trick: Make a backup copy of your .xlsx file. Change the file extension from .xlsx to .zip. Open the ZIP folder and navigate to xl > worksheets. Open your protected sheet (e.g., sheet1.xml) using Notepad.
Press Ctrl + F, search for the tag < to the closing >.
Save the text file, replace it back in the ZIP archive, and rename the file extension back to .xlsx. The worksheet is now completely unprotected.
If you would like to proceed with solving your file access issues, please let me know:
Is your file locked with a “Password to Open” or just restricted from editing/sheets modification?
