Is the YAML to JSON converter free?

Yes, completely free with no signup required.

All conversion happens in your browser using js-yaml. Your file never leaves your browser.

What YAML features are supported?

Anchors, aliases, multi-line strings, block/flow scalars, sequences, mappings, comments (stripped in JSON output), and YAML 1.2 types.

Are YAML comments preserved in JSON?

No. JSON does not support comments, so YAML comments are stripped during conversion.

Can I convert multi-document YAML?

Yes. Separate multiple YAML documents with --- and the tool converts the first document. Use the JSON to YAML tool to go back.
