Why does my YAML have quotes around some strings but not others?

YAML quotes strings that would otherwise be misinterpreted — e.g. 'true' (would be boolean), '123' (would be number), strings with special characters. The converter adds quotes only where necessary to preserve the JSON type.

Can all JSON be converted to YAML?

Yes — YAML is a superset of JSON, so every valid JSON document is also valid YAML. The reverse is not true: YAML features like anchors, multi-document streams, and tags have no JSON equivalent and may be lost or rejected.

Convertir JSON to YAML and back without losing data

Translate entre JSON et YAML pour config fichiers, preserving nested structures, tableaux, et scalar types across le round-trip.

YAML is a superset of JSON with indentation-based structure and fewer brackets — preferred for human-edited config. Converting JSON→YAML makes config readable; YAML→JSON makes it machine-parseable. The conversion must preserve types, nesting, and arrays.

Convertisseur JSON ↔ YAML →
Paste JSON. The tool outputs equivalent YAML with 2-space indentation, block style for maps and sequences, and proper quoting only where needed.

Use the chain to convert JSON→YAML and immediately validate the YAML parses back to the same structure.

Inverser direction: paste YAML, get JSON. Useful when a tool expects JSON input but your source is a YAML config.

Watch for YAML-specific gotchas: unquoted strings that look like booleans (yes/no/on/off), numbers with leading zeros (interpreted as octal in YAML 1.1), and multi-line string folding. Quote ambiguous scalars to be safe.
