How it works

This tool uses PapaParse for robust CSV parsing that handles quoted values, multi-line fields, and various delimiters. When "first row is header" is enabled, each row becomes a JSON object with keys from the header row. Otherwise, rows become arrays.

🔒 Privacy

All CSV parsing and JSON conversion happens in your browser. Your data never leaves the page.
