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.
