## About

## What it does

JSON to CSV converts JSON objects and JSON arrays into CSV, so you can turn structured data into a flat table for spreadsheets, warehouses, and downstream tools. Send raw JSON, upload a `.json` file, or point the service at a public JSON URL, and choose an inline response, a downloadable file, or a pre-signed S3 URL.

Use JSON to CSV when you need to export API responses, normalize webhook payloads, or hand data off to analysts who expect CSV. The raw JSON endpoints accept either a single JSON object with at least one property or a non-empty array of JSON objects. The file and URL-based endpoints accept a JSON file with MIME type `application/json`, or a public URL that serves JSON with `application/json`, `text/plain; charset=UTF-8`, or a `.json` file content-disposition.

The output is either CSV text, a downloadable CSV file, or an object containing `data`, a pre-signed S3 URL to the converted file. Pick the response shape that fits your pipeline: stream the CSV directly into your app, let users download it, or store it in object storage for later processing.
