YAML to JSON examples

Convert a small YAML object

YAML configuration can be converted into JSON for APIs, test fixtures, or tooling that does not accept YAML.

Input

name: LocalTools

  - privacy
  - developer

Output

{
  "name": "LocalTools",
  "tags": [
    "privacy",
    "developer"
  ]
}

YAML to JSON use cases

  • Convert configuration snippets into JSON for docs or API tests.
  • Inspect YAML structures with JSON indentation.
  • Normalize small YAML examples before pasting them into code.

How YAML to JSON works

  • The YAML input is parsed with the browser-loaded parser.
  • The parsed value is serialized as formatted JSON.
  • The conversion runs locally after the page loads.

YAML to JSON mistakes to avoid

  • Indentation changes YAML meaning.
  • Tabs are a common cause of YAML parsing failures.
  • Advanced YAML features such as anchors can surprise downstream JSON consumers.

YAML to JSON FAQ

Can every YAML file become JSON?

Most ordinary maps, arrays, strings, numbers, and booleans convert cleanly. YAML features without a JSON equivalent may need cleanup.

Is the YAML uploaded?

No. The conversion runs in your browser.
