How to Convert YAML to JSON

Method 1: Use the online converter (recommended)

1. Open the YAML to JSON converter.
2. Paste your YAML into the left box.
3. The JSON output appears on the right automatically.
4. Copy or download the result.

Everything runs in your browser, so your data never leaves the page.

Method 2: Convert with a code snippet

In Node.js with js-yaml installed:

const yaml = require('js-yaml');
const json = JSON.stringify(yaml.load(yamlText), null, 2);

Common gotchas

• Indentation matters. YAML uses spaces, not tabs.
• Duplicate keys are invalid and will error.
• Booleans/numbers are inferred automatically (e.g. true, 42).

Not sure your YAML is valid? Run it through the YAML validator first.
