# YAML ↔ JSON Convert YAML to JSON and back, entirely in your browser using a self-contained parser. Nothing is uploaded. ### How it works YAML and JSON describe the same data model, so conversion is a parse-and-re-serialise. This tool uses the well-known open-source **js-yaml** parser, embedded directly in the page (no external requests), to read YAML into an object and print it as JSON — and the reverse. All processing happens on your device. --- *Source: [ocxly.com/yaml-json.html](https://ocxly.com/yaml-json.html) — OCXLY, free 100% client-side privacy-first tools.
