Privacy: conversion runs locally in your browser. No JSON or CSV content is stored or transmitted.

The converter reads a JSON array of objects, gathers all keys, creates a header row, and writes each object as a CSV row using the selected delimiter.

Examples

  • [{"name":"Alex","age":30}] → one-row CSV with header
  • [{"id":1},{"id":2}] → repeated key column output
  • Nested values are stringified when needed
