How to convert YAML to JSON

  1. Choose a direction (YAML to JSON or JSON to YAML).
  2. Paste your YAML or JSON.
  3. Select Convert.
  4. Copy the result.

How this works

Your browser parses the input using a standard, widely-used open-source YAML parser running entirely client-side — no file is uploaded, and no server-side processing is involved.

Common use cases

  • Convert a YAML config file into JSON for a tool that only accepts JSON
  • Convert a JSON API response into YAML for readability
  • Quickly validate YAML syntax by converting it

Frequently asked questions

Is this YAML to JSON converter free?

Yes. It is completely free, with no signup and no limits.

Is my data uploaded anywhere?

No. Conversion happens entirely in your browser. Nothing is sent to Inqita or stored.

Does this validate my YAML or JSON?

Yes — invalid syntax shows a clear error message rather than a silently wrong result.

Does this support YAML anchors and references?

Yes — the underlying parser supports standard YAML features including anchors, aliases, and multi-document handling for the fields JSON can represent.
