About YAML to JSON

YAML is comfortable to write for configs and CI pipelines, but many tools, APIs, and validators expect JSON. Eyeballing indentation to mentally translate YAML into JSON is exactly the kind of thing that hides bugs. This converter parses your YAML and emits the equivalent JSON, so you can feed it to a service or just confirm your YAML means what you think it does.

Paste your YAML and the tool resolves its mappings, sequences, and scalar values into a JSON object or array. It runs free in your browser with no signup and returns output instantly. Because YAML is indentation-sensitive, keep your spacing consistent, and you will get JSON that matches the structure you intended.

Common uses

  • Converting a YAML config into JSON for a tool that only accepts JSON
  • Validating that your YAML parses by seeing its JSON equivalent
  • Turning Kubernetes or CI YAML into JSON for inspection or processing
  • Embedding YAML-authored data into a JSON-based API payload
  • Comparing two configs by converting both to a normalized JSON form

FAQ

Does it support multi-document YAML?

Single documents convert most reliably. If you have multiple documents separated by ---, convert them one at a time for predictable JSON.

Are YAML anchors and aliases expanded?

References are generally resolved into their concrete values, so the JSON contains the fully expanded structure.

Why does my output look different from the YAML order?

JSON objects do not guarantee key order in every consumer, though the values and nesting match your YAML exactly.

What if my indentation is inconsistent?

YAML relies on indentation, so uneven spacing can change the structure or cause a parse error. Keep it consistent.

Can I use YAML to JSON on mobile?

Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
