YAML to JSON Converter

Paste YAML and get structured JSON back. Handy for debugging CI configs, feeding YAML into a tool that only speaks JSON, or just inspecting what your config actually resolves to.

Pengenalan alat

Paste YAML and get structured JSON back. Handy for debugging CI configs, feeding YAML into a tool that only speaks JSON, or just inspecting what your config actually resolves to.

Gambaran keseluruhan alat

The converter tokenizes your YAML line by line, tracks indentation to build the hierarchy, and resolves scalars to their JSON-native types (numbers, booleans, null, strings). Both block style (indented) and flow style ([a, b] / {k: v}) mappings and sequences are supported, along with comments, single- and double-quoted strings, and the usual `null`/`~`/`true`/`false` aliases.

Kes penggunaan

Inspect a Kubernetes manifest as JSON
Pipe a YAML config into jq or a JSON Schema validator
Convert Docker Compose files for tools that require JSON
Debug why a CI config is being parsed a certain way

Contoh input/output

Niat input

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

Niat output

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

Comments are stripped and flow-style arrays are supported.

Niat input

# deployment config
image: nginx:1.25
ports: [80, 443]
labels:
  app: web
  tier: frontend

Niat output

{
  "image": "nginx:1.25",
  "ports": [80, 443],
  "labels": {
    "app": "web",
    "tier": "frontend"
  }
}

Scalars resolve to their JSON-native types.

Niat input

greeting: 'hello world'
count: 42
enabled: true
nothing: null

Niat output

{
  "greeting": "hello world",
  "count": 42,
  "enabled": true,
  "nothing": null
}

Soalan lazim

Is this YAML to JSON converter free?+

Yes. It runs entirely in your browser, with no sign-up, no file-size gates, and no ads inside the tool.

What subset of YAML is supported?+

Block and flow mappings/sequences, plain and quoted scalars, comments, and null/boolean/number resolution. Anchors (&), aliases (*), tags (!!type), and multi-line scalars (|, >) are not yet supported.

Will it coerce numeric strings like "007"?+

Leading-zero strings are kept as strings. Only values that match a strict integer or float pattern are converted to numbers.

Is my data sent to a server?+

No. Parsing and conversion happen entirely in your browser — the page never talks to a backend.

Can I convert Kubernetes, Docker Compose, or GitHub Actions YAML?+

Yes. Those configs use the block/flow features this converter supports. Paste the file and the resulting JSON is ready for jq, JSON Schema validators, or direct import into code.
