JSON Input

CONVERT

Accepts a flat JSON array of objects. Nested values are converted to strings.

Runs entirely in your browser

How it works

The JSON array is parsed with the native JSON.parse API, then each object is serialised into a CSV row, with values containing commas or quotes automatically escaped. All processing 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.
