About this tool

YAML is stricter than it looks: an unquoted 123 is a number, "true" is a boolean, and a colon inside a plain string ends the value early. This converter quotes any string that would change meaning on the way back, nests objects and arrays with standard two-space indentation, and keeps empty objects and arrays in their compact {} and [] forms.
