Pengantar alat

Gambaran alat

YAML is the de-facto config format for CI/CD pipelines and infrastructure-as-code because it is easier for humans to scan than JSON. This converter reads your JSON with the strict built-in parser, then emits YAML using plain-style scalars where safe and double-quoted strings when a value is ambiguous (looks like a number, boolean, or reserved keyword). Nested objects become block mappings, arrays become sequences, and empty collections collapse to `{}` or `[]`.

Contoh input/output

Maksud input

{"name":"api","replicas":3,"env":["prod","staging"]}

Maksud output

name: api
replicas: 3
env:
  - prod
  - staging

Strings that look like numbers (like "3") are quoted so they round-trip safely.

Maksud input

{"version":"3","services":{"web":{"image":"nginx","ports":["80:80"]}}}

Maksud output

version: "3"
services:
  web:
    image: nginx
    ports:
      - "80:80"

Top-level JSON arrays become block sequences.

Maksud input

[{"id":1,"active":true},{"id":2,"active":false}]

Maksud output

- id: 1
  active: true
- id: 2
  active: false

Pertanyaan umum

Is my JSON uploaded anywhere?+

No. The conversion runs 100% in your browser — nothing is transmitted to a server, logged, or stored.

Is this JSON to YAML converter free?+

Yes. Every UtilitySansar tool is free, unlimited, and has no ads inside the tool area.

Why are some of my strings quoted in the output?+

Values that look like numbers, booleans, null, or contain characters YAML treats specially (:, #, -, leading spaces) are double-quoted so they round-trip back to the same JSON value.

Does it support YAML anchors, tags, or multi-line scalars?+

Not yet. The output uses block and flow scalars only, which covers the vast majority of real-world Kubernetes, GitHub Actions, and Docker Compose configs.

What indentation does it use?+

Two spaces per level, matching the default for Kubernetes, GitHub Actions, Ansible, and most YAML style guides.
