Convert JSON into clean, readable YAML with type-preserving quoting — processed entirely in your browser.
Your YAML will appear here after you convert.
YAML is a superset-friendly, indentation-based format that many developers find easier to read and edit than JSON, especially for configuration. Converting lets you turn JSON data or API responses into clean YAML config.
{
"name": "John",
"active": true,
"roles": ["admin", "editor"]
}name: John
active: true
roles:
- admin
- editorYAML powers CI pipelines, Kubernetes manifests, and countless app config files. Its lack of braces and quotes makes hand-editing pleasant, while still mapping cleanly to the same object/array model as JSON.
YAML infers types from unquoted scalars, so a value like true, 123, or 00123 could change meaning if written naively. This converter quotes such strings automatically, so the YAML parses back to exactly the same data — YAML to JSON confirms the round trip. Start from clean input with the JSON Formatter.
YAML is widely used for configuration files (CI pipelines, Kubernetes, app config) because it is easier to read and edit than JSON. Converting lets you reuse existing JSON data as YAML config.
Yes. The serializer quotes values when needed so they keep their meaning — for example the string "true", "123", or "00123" is quoted so it is not read back as a boolean or number.
Yes. For supported JSON structures, JSON → YAML → JSON preserves the data. This is covered by automated round-trip tests.
Objects become indented mappings and arrays become block sequences (dash-prefixed items). You can choose 2- or 4-space indentation.
No. Conversion happens entirely in your browser.
