FAQ

What is the difference between Excel and CSV?+
Excel files (XLSX, XLS) support formatting, formulas, charts, and multiple sheets. CSV files are plain text with comma-separated values — no formatting, just pure data. CSV is universally compatible with databases, programming languages, and data tools.
Can I convert a password-protected Excel file to CSV?+
This tool works with unprotected Excel files. If your file is password-protected, you'll need to remove the password first. We offer a free Decrypt Excel tool that can help with that.
Will my CSV file have the same column order as Excel?+
Yes. The column order in your CSV output matches exactly what you see in your Excel spreadsheet. No columns are reordered, added, or removed during the conversion.
