JSON to CSV

Paste a JSON array of objects, get a CSV table back. Works both directions.

Converting between JSON and CSV is a routine task when moving data between an API and a spreadsheet, or preparing data for import into a tool that only accepts one format.

How it works

  1. Paste your dataA JSON array of objects, or a CSV table.
  2. Pick a directionJSON → CSV or CSV → JSON, both work.
  3. Copy the resultGrab the converted data straight from the box.

Good to know

  • Values containing commas or quotes are handled correctly — they're quoted and escaped per the CSV standard, not left broken
  • JSON input should be an array of objects; the first object's keys become the CSV header row
  • Missing fields in some objects become empty cells rather than shifting columns
  • Works both directions on the same page — no separate tool needed

FAQ

An array of flat objects with the same keys, like [{"a":1,"b":2}] — nested objects and arrays inside fields aren't flattened.
