How it works

How it works

This tool supports a tiny, safe subset of YAML for quick conversions.

  • Keys map to values with key: value. Nesting is by 2‑space indentation.
  • Arrays use - item per line or flow [a, b] notation.
  • Scalars: numbers, booleans, null; strings are unquoted unless they contain special characters.

Unsupported: anchors/aliases, block scalars (|, >), tags, complex types, comments preservation.

Privacy & Security

All parsing is in-browser.

Accuracy, Limits & Tips

No anchors, block scalars, multi-line strings, flow mappings. Use for simple snippets only.

Examples

  • Convert small config fragments.
