Cleaner DevOps configs
Kubernetes, CI, and app settings are easier to review when indentation is consistent. Format Convertly re-indents a practical YAML subset locally.
Dependency-free parser
We use the same style of browser YAML support as our converters — enough for everyday maps, lists, and scalars without shipping a large library.
Pair with validation
If formatting fails, the YAML validator helps you locate structural problems before deploy.
