Paste or type JSON in the left panel and get clean, readable YAML on the right. Conversion is instant — no button to press. You can copy the result to clipboard or download it as a .yaml file.
YAML is a superset of JSON and is often preferred for configuration files because it is less cluttered — no quotes around keys, no commas, and support for comments. Tools like Docker Compose, Kubernetes, GitHub Actions, and Ansible all use YAML. If your JSON is destined for a config file, YAML is usually the more readable choice.
Paste your JSON into the left panel. The converter parses it and uses js-yaml to produce equivalent YAML in the right panel. The conversion is real-time — output updates as you edit.
Yes. Nested objects become indented YAML mappings, and JSON arrays become YAML sequences. All standard JSON types — strings, numbers, booleans, null, objects, and arrays — are handled correctly.
Not directly in this tool. This converter is one-way: JSON → YAML. A YAML to JSON converter will be available as a separate tool.
The data is identical. YAML drops the curly braces and square brackets used in JSON and replaces them with indentation. Quoted strings in JSON may appear unquoted in YAML if they don't need escaping.
No. Conversion happens entirely in your browser using the js-yaml library. Your data never leaves your machine.
