JSON to YAML,
explained.
Is every JSON file valid YAML?+
JSON is a subset of YAML, but this tool rewrites it into the more readable block-style YAML commonly used in configuration files.
Will key order stay the same?+
Yes. Object keys are emitted in the order supplied by the JSON parser.
Are my files uploaded?+
No. TidyFormat processes the conversion locally in your browser. Your input and output files are not sent to our servers.
