YAML to JSON & JSON to YAML Converter
Converts YAML to JSON with yaml.load, or JSON to YAML with yaml.dump. A parse error is shown.
How to use YAML ↔ JSON
- Choose the conversion direction.
- Paste the source document.
- Generate and inspect types and values.
A practical example
The YAML mapping enabled: true converts to a JSON boolean, not the string "true".
What to check before using the result
Data conversion does not preserve comments or formatting. YAML-specific types may not have JSON equivalents.
