YAML & JSON Converter questions
Does it support full YAML?
No. It supports a simple readable subset: objects, arrays, strings, numbers, booleans, and null.
Can it convert nested JSON?
Yes. JSON objects and arrays are converted to indented YAML.
Is this tool free?
Yes. The current Toolkits tools are free to use and do not require an account. If advertising is added later, it should be clearly labeled and kept away from primary tool controls.
