JSON ⇄ YAML FAQ
Is the conversion lossless?
JSON → YAML is always lossless. YAML → JSON is lossless for the JSON-compatible subset; YAML-only features like anchors are resolved and comments are dropped.
Which YAML version is supported?
The parser follows YAML 1.2, which is a strict superset of JSON — any valid JSON is also valid YAML input.
Can I convert YAML back to JSON?
Yes, the tool is bidirectional. Paste YAML on the right and hit "YAML → JSON".
Is my data uploaded?
No. Both directions run entirely in your browser.
