Frequently asked questions

Are comments and multiline strings retained?

The formatter supports comments, anchors, aliases, and multiple documents. Quote and line-break styles may change, so review configuration files before using the result.

Can I indent YAML with tabs?

YAML indentation uses spaces. Choose two or four spaces in this tool.

Does this validate my configuration?

It checks YAML syntax, not duplicate keys, service-specific schemas, or required configuration fields.
