Understanding XLS vs XLSX Formats

Before choosing a password remover, it's crucial to understand the difference between XLS and XLSX formats, as this affects which tools and methods work best:

Frequently Asked Questions

What's the difference between XLS and XLSX password removal?

XLS (legacy format) uses weaker RC4 encryption, making password removal generally faster (1-2 seconds). XLSX uses stronger AES encryption but modern tools handle both equally well. The main difference is XLS is limited to Excel 2003 compatibility while XLSX is the current standard.

Can I remove passwords from Google Sheets exports?

Yes! Google Sheets files exported to Excel format (.xlsx) can have passwords removed using the same tools. Export your Google Sheet as XLSX, remove the password using Excel-Decoder.Online, then re-upload to Google Sheets if needed.

Do spreadsheet password removers work for LibreOffice Calc files?

LibreOffice Calc uses .ods format natively. To remove passwords, first export the file as .xls or .xlsx from LibreOffice, then use Excel password removal tools. The converted file can be opened back in LibreOffice after password removal.

Which is faster: XLS or XLSX password removal?

XLS password removal is typically faster (1-2 seconds) due to older, simpler encryption. XLSX may take 2-3 seconds due to AES encryption. However, with modern online tools like Excel-Decoder.Online, the difference is negligible for most users.

Should I convert XLS to XLSX after removing passwords?

Yes, converting to XLSX is recommended unless you need Excel 2003 compatibility. XLSX offers better compression (smaller file size), improved data recovery, enhanced security features, and support for larger datasets. Excel 2007 and newer fully support XLSX.

Will password removal work on files from WPS Office or Apple Numbers?

Yes! WPS Office uses standard Excel formats (.xls/.xlsx), so password removal works identically. For Apple Numbers, export the file to Excel format first, remove the password, then optionally convert back to .numbers format using Numbers app.

Can I remove passwords from multiple XLS files at once?

Excel-Decoder.Online processes files individually for security. For batch processing, you'll need desktop software like PassFab or iSunshare which support bulk operations. However, most users find individual processing fast enough (1-2 seconds per file).

Are my spreadsheet files safe when using online password removers?

Reputable tools like Excel-Decoder.Online use HTTPS encryption for uploads/downloads and automatically delete files after processing (typically within seconds). However, avoid uploading highly sensitive financial or personal data to any online service as a general security practice.

Conclusion

XLS password removal and universal spreadsheet password removal have become incredibly simple in 2025. Whether you're working with legacy XLS files from Excel 2003, modern XLSX files, or exports from Google Sheets and LibreOffice, the right tools make password removal instant and effortless.

While XLS files use older encryption that's generally faster to crack, modern online tools like Excel-Decoder.Online handle both XLS and XLSX formats with equal efficiency - typically delivering results in 1-3 seconds. The key is choosing a reliable, secure tool that supports multiple formats and works across all platforms without installation.
