For stronger encryption, the service is typically far more affordable than purchasing standalone software, making it a low-risk investment for a one-time recovery.
Is LostMyPass the best MS Excel password recovery tool? It is the best for convenience and older file formats. For users who are not tech-savvy or those dealing with legacy .xls files, it offers a quick, often free solution without the hassle of installation.
However, for modern .xlsx files containing highly sensitive data, offline desktop software remains the superior choice regarding data security and long-term cost.

Forgetting an Excel password can bring your productivity to a screeching halt. While there are many software options you can download, LostMyPass offers a strictly online solution using high-powered GPU clusters to crack encryption without requiring you to install anything on your machine. How It Works
LostMyPass uses distributed GPU servers to test millions of password combinations per second. It supports three primary recovery methods:
Weak Password Recovery: Checks your file against a database of roughly 3 million common passwords. This process is usually fast and free.
Strong Password Recovery: A paid service that uses more intensive brute-force and dictionary attacks. It boasts a success rate of approximately 61%.
Brute Force with Mask: If you remember parts of your password (like "it starts with 'S' and is 8 characters long"), this method narrows the search to save time. The Pros and Cons Pros Cons
No Software Required: Completely browser-based; no risk of installing malware.
Security Risks: You must upload your sensitive data to a third-party server.
Pay-on-Success: For strong recovery, you typically only pay if they actually find the password.
File Size Limits: Files are generally restricted to under 100MB. GPU Power: Much faster than a standard home office PC.
Success Not Guaranteed: Complex passwords may still be unrecoverable. Success Rates and Pricing
Free Version: Has a success rate of about 22% for simple or common passwords.
Paid Version: Costs start around £24 ($30) with a 61% success rate for more complex "Strong" recovery tasks.
Recovery Speed: While simple passwords take minutes, complex six-character passwords can take up to three days—though this is still significantly faster than the months it would take on a standard PC. Top Alternatives lostmypass ms excel password recovery best
If you aren't comfortable uploading your data to the cloud, consider these local software alternatives:
Passper for Excel: A downloadable tool that recovers "Open" passwords and can instantly remove editing restrictions.
PassFab for Excel: Similar to Passper, offering a free trial and various "attack" modes for decryption.
Passware Kit: A professional-grade option (starting at $49) used by forensics experts for over 80 file types.
Accent EXCEL Password Recovery: Specifically optimized for high-speed recovery on both Intel and AMD processors. The Verdict
LostMyPass is an excellent "first-response" tool if your password might be simple or if you don't want to install software. However, for highly sensitive business data, a local tool like Passper for Excel or Passware may be safer since the file never leaves your computer. Best password recovery tools | IT Pro - ITPro

One-Off Home Use: LostMyPass is ideal for non-sensitive personal documents where you don't want to install software.
Sensitive/Corporate Data: For highly sensitive files, experts recommend desktop-based tools like Passper for Excel or SysTools Excel Password Recovery because online tools require uploading your file to their servers. Free Alternatives:
Google Sheets: For simple sheet protection, uploading the file to Google Sheets and downloading it again as a new Excel file can sometimes strip the protection.
VBA Macros: If the workbook is open but specific sheets are locked, various free VBA scripts found on Spiceworks or Reddit can find a working password bypass.
