## About

## What it does
JSON to YAML Converter turns JSON into YAML and returns it as either a downloadable file, raw text, or a pre-signed S3 URL. You can send JSON as an uploaded file, pass a public JSON URL, or submit a raw JSON body.

Use the file-based endpoints when you want a `.yaml` download, the raw-text endpoints when you want YAML inline in the response, and the URL endpoints when your workflow stores the converted file in S3. The URL inputs accept publicly accessible JSON resources, and the uploaded-file endpoints require a JSON file with `application/json` mimetype.

This is useful when you need to convert configuration files, sample payloads, or API responses from JSON into YAML for documentation, tooling, or manual review. Send a JSON object and get the same data back in YAML form, without changing the structure by hand.

The service also includes raw-body conversion for non-empty JSON objects, so you can post structured data directly when you already have the payload in your request.
