What a YAML actually stores
YAML records a tree of data where the meaning is carried by indentation. That makes it readable to a person and slightly awkward to a model, which does better with an explicit hierarchy than with one implied by whitespace it has to count.
Asking a model to review a CI pipeline, a Kubernetes manifest or a Docker Compose file is a common thing to want, and deep YAML pasted raw is where models most often lose track of which key belongs to which parent.
What survives the conversion
The full structure. Nested mappings become nested headings or lists depending on depth, sequences become bullets, and scalar values stay attached to their keys. Comments are kept, because in a config file the comment explaining why a value is what it is is frequently the most important line.
What does not
Anchors and aliases are expanded where they can be resolved and otherwise left as written, rather than being silently dropped. Multi-document streams separated by three dashes are converted in order but lose the fact that they were separate documents. Nothing here re-types your values: YAML famously reads the unquoted word <em>no</em> as a boolean, and a converter that quietly resolved that ambiguity would be making a decision that belongs to you.
Saying so plainly is deliberate. A converter that quietly drops half a document is worse than one that tells you which half, because you can work around a limit you know about.
Questions
Why convert YAML at all — is it not already readable?
Readable to you, ambiguous to a model. Indentation-based nesting has to be counted rather than seen, and in a file a few hundred lines deep that is exactly where a model starts attributing a setting to the wrong parent.
Are comments kept?
Yes. In configuration the comment is often the only record of why a value was chosen, and stripping it would remove the part a reviewer most needs.
Does it validate my YAML?
No. It converts what parses and tells you when something does not. A linter is a different tool and a better one for that job.
Converting a different format
The same engine handles eighteen formats in total, all of them in your browser.
