YAML to JSON

Convert YAML data to JSON locally

YAML

Paste YAML directly or import a .yaml or .txt file from this device.

What this tool is for

Use this tool when you need to turn valid YAML into JSON that is easier to scan, share, or commit. Everything runs locally in the browser.

Where it helps

  • Convert API examples to JSON for documentation or configuration files.
  • Convert YAML into a format that is easier to compare.
  • Prepare data for tools and workflows that require JSON.

What to watch for

  • Input must be valid YAML.
  • The converter preserves the data structure, but the JSON formatting may differ from your preferred style.
  • If you need to go the other direction, use the JSON to YAML converter instead.
