Is the YAML output guaranteed valid?

Yes. If the input JSON is valid, the output YAML is structurally correct.

Can I choose YAML indent (2 or 4 spaces)?

Yes. Use the YAML indent option to output 2 or 4 spaces. You can also download the result as a .yaml file.

Is this safe for proprietary configs?

Yes. Conversion is local so your configs stay private.

Do I need to format the JSON first?

No. The tool accepts minified or unformatted JSON.

JSONをYAMLに
