常见问题
›What YAML version is supported?
YAML 1.2 — the modern superset of JSON. Anchors, references, multi-line strings and nested structures all work.
›Are comments preserved?
No — JSON doesn't support comments, so they're stripped on conversion.
›What if my YAML is invalid?
You'll see a clear error with the line and column. Common issues: tabs (use spaces), inconsistent indentation, unquoted special chars.
›Is my YAML uploaded?
No — runs entirely in your browser.
›Is the converter free?
Yes — fully free, no signup.
