Frequently Asked Questions
What YAML features are supported?
Full YAML 1.2 via js-yaml: anchors, aliases, multi-line strings, all scalar types. YAML-specific types (e.g. !!binary) are not preserved in JSON.
Is my data sent to a server?
No. All conversion happens in your browser. Nothing is transmitted.
Can I also convert JSON back to YAML?
Yes — switch to the JSON → YAML direction in the same tool, or visit the JSON to YAML converter page.
