Why this tool exists

Get the answer without turning it into a project.

Useful for application config, CI files and infrastructure snippets. The lightweight parser focuses on everyday mappings and keeps processing local.

Common questions

Does it support the entire YAML specification?

No. The local lightweight parser targets common mappings and scalar values. Complex anchors, tags and advanced YAML syntax are intentionally out of scope.

Can JSON arrays be converted to YAML?

Yes. JSON arrays are emitted as YAML list items.
