YAML to JSON
Need JSON for an API mock or unit test fixture? This free YAML to JSON converter turns YAML documents into pretty-printed JSON in one click. Multi-document files become JSON arrays so nothing is dropped.
Ops and platform engineers paste manifests locally without leaking cluster details to a third-party upload service. If parsing fails, the error includes line and column - or validate first with our YAML Validator, then convert.

Frequently Asked Questions
What if my file has multiple YAML documents?
Multi-doc streams (---) become a JSON array of documents. Single documents become a single JSON value.
Are YAML anchors supported?
js-yaml resolves anchors/aliases into concrete values in the resulting JSON.
Why did conversion fail on line N?
Indentation or tab/space mixing usually causes this. Fix the reported line, or validate first with the YAML Validator.
Does this send my YAML to a server?
No. Conversion is fully client-side for privacy.
