Runs entirely in your browser
How it works
The CSV is parsed field-by-field in JavaScript, handling quoted fields, embedded commas, and escaped quotes. The first row becomes the object keys. All parsing runs locally in your browser.
Processing runs in your browser
All conversion happens inside your browser tab using JavaScript. Our servers are not involved at any point.

After converting, pretty-print or minify the output with the JSON formatter. For escaping commas or quotes inside cells, try URL encode. To convert formatted SQL dumps into rows, see the SQL formatter.
Frequently asked questions

- Is my CSV data uploaded?

- What if my CSV has no header row?
