## About

## What it does
JSON to CSV converts JSON objects, JSON arrays, or JSON files into CSV output. You can send raw JSON in the request body, upload a JSON file, or point the service at a public JSON URL, then choose whether you want the result inline, as a downloadable file, or as a pre-signed S3 URL.

Use JSON to CSV when you need to flatten API responses, export records for spreadsheets, or move structured data into tools that expect comma-separated values. The raw-body endpoints accept either a JSON object with at least one property or a non-empty array of JSON objects. The file and URL endpoints accept JSON input from an uploaded file or a public URL, and the file-based responses return a downloadable CSV binary.

If you need a URL-based workflow, the signed-URL variants return an object with a `data` field containing a pre-signed S3 URL to the converted file. If you prefer to handle the output directly in your app, use the inline endpoints, which return the CSV as a string.

JSON to CSV is a practical fit for reporting pipelines, lightweight ETL jobs, admin exports, and any integration where tabular output is easier to store or review than nested JSON.
