About this tool

YAML is the indentation-based format behind Docker Compose, Kubernetes manifests and CI configs. This parses nested maps, lists and scalars, converting cleanly in either direction.

What's supported

Block-style maps/lists (incl. lists of maps), quoted/unquoted strings, numbers, booleans, null, and whole-line comments. Flow style like {a: 1} isn't supported. Nothing is uploaded.
