Excel to CSV Converter
Turn an Excel sheet into a CSV file.
Quick answer: Choose an .xlsx or .xls file, pick CSV and press Convert. Every sheet can be converted. Nothing is uploaded.
🔒 Your files stay on your device. Nothing is uploaded, and nothing is saved or kept on our side.
How to use it
- Choose a file or drop it on the box.

Formulas are saved as their last calculated values. The CSV is saved as UTF-8 with a byte-order mark so Excel opens accented letters correctly.
