JSON to YAML

Convert JSON to readable YAML

JSON is precise but noisy to read and edit by hand. YAML expresses the same data with indentation instead of brackets and quotes, which is why configuration files, pipelines and infrastructure definitions use it. JSON to YAML converts a JSON file into clean YAML without changing a single value.

Paste the JSON or drop a .json file. Objects become mappings, arrays become sequences, and strings, numbers, booleans and null keep their types. Key order is kept as it is in the JSON, so a configuration file stays in the order you wrote it. Strings that YAML would otherwise read as something else, such as yes, no, null or 1.0, are quoted so that reading the YAML back gives exactly the original data. Unicode is written as it is, not escaped, so names and labels in any language stay readable. Long text is not wrapped.

Invalid JSON is reported with the line and column of the mistake, and the JSON Formatter can repair common problems such as trailing commas first. YAML to JSON converts in the other direction, and Compare JSON shows the differences between two configurations before you deploy them.
