JSON to CSV
Convert a JSON array of objects into CSV output. Choose a delimiter and include headers automatically.
Input must be a JSON array of objects. Mixed value types are supported, but nested objects may be stringified.
| Metric | Value |
|---|
Privacy: conversion runs locally in your browser. No JSON or CSV content is stored or transmitted.
How it works
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
