About YAML Parser & Serializer
YAML (YAML Ain't Markup Language) is a human-friendly data format, widely used for configuration. This tool parses YAML into JSON (for programs to process) and back.
Use "YAML → JSON" mode to see a YAML structure as JSON, or "JSON → YAML" to produce YAML from JSON data. Use it to debug configuration files.
Everything runs in the browser using the js-yaml library. For direct conversion to other formats, see the JSON ⇄ YAML converter.
FAQ
Is my data sent to a server?
No. YAML Parser & Serializer runs entirely in your browser using client-side libraries. Your data never leaves your device.
