Frequently Asked Questions

JSON and YAML conversion explained.

What is YAML?

YAML (YAML Ain't Markup Language) is a human-readable data serialization format. It uses indentation instead of brackets/braces and is widely used for config files (Kubernetes, Docker Compose, GitHub Actions, Ansible).

Is YAML a superset of JSON?

Yes. Valid JSON is valid YAML 1.2. YAML adds features like comments (#), multi-line strings (|, >), anchors (&) and aliases (*), and more flexible key/value syntax.

Why does YAML sometimes look different from what I expect?

YAML has special handling for strings that look like booleans (yes, no, true, false, on, off) or numbers. js-yaml uses YAML 1.2 spec which fixes most of these edge cases, but you may need to quote ambiguous values.

Can I convert YAML with comments to JSON?

Comments are stripped during YAML-to-JSON conversion — JSON does not support comments. The semantic data is preserved; only the comment text is lost.

What about YAML anchors and aliases?

YAML anchors (&anchor) and aliases (*anchor) are resolved during parsing. The output JSON (or YAML) will contain the dereferenced values — anchors are not preserved in the output.
