First row is used as object keys. Quoted fields with commas are handled correctly.

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

Does it handle quoted fields?
Yes. Fields wrapped in double quotes are parsed correctly, including commas and newlines inside quotes.
Is my CSV data uploaded?
All parsing happens in JavaScript inside your browser tab. Our servers are not involved at any point.
What if my CSV has no header row?
The first row is always used as keys. If your CSV has no header, add one manually before pasting.
What format is the JSON output?
An array of objects, one per data row. Each object's keys come from the header row.
