Frequently asked questions
Why can YAML fail even when it looks correct?+
Indentation is structural in YAML. Tabs, inconsistent spacing or an unquoted special value can change or invalidate the document.
Are YAML comments kept in JSON?+
No. JSON has no comment syntax, so comments are not represented in the converted data.
Can I convert Kubernetes or CI configuration?+
Yes, provided the input is valid YAML. Always review generated JSON before using it in production.
