How to use this tool
Paste JSON and choose indentation width. Check quoting of date-like or numeric-looking strings with the destination YAML parser before using configuration output.
Results and examples
{"enabled":true,"name":"01"} distinguishes a Boolean enabled value from the string name. Parse the generated draft again to confirm that the intended types survive.
