YAML to JSON Converter

Convert YAML to JSON format instantly. Works with Kubernetes, Docker, Ansible, and any YAML document.

How YAML Maps to JSON

YAML and JSON represent the same data model. The conversion is lossless for standard YAML documents:

  • YAML key-value pairs → JSON object properties
  • YAML sequences (- item) → JSON arrays ([])
  • YAML strings, integers, floats, booleans, and null → equivalent JSON types
  • Indented YAML blocks → nested JSON objects

Example

Input YAML:

name: John Smith
age: 30
skills:
  - JavaScript
  - Python

Output JSON:

{
  "name": "John Smith",
  "age": 30,
  "skills": [
    "JavaScript",
    "Python"
  ]
}

Frequently Asked Questions

Can I convert Kubernetes YAML to JSON?

Yes. Paste any Kubernetes manifest, Helm values file, or Docker Compose YAML and the tool converts it to JSON, preserving all nested objects, arrays, and data types.

Does YAML to JSON preserve data types?

Yes. YAML strings → JSON strings, integers and floats → JSON numbers, true/false → JSON booleans, null → JSON null. The conversion is type-safe.

Is my YAML data sent to a server?

No. All conversion happens entirely in your browser. Your data never leaves your device.
