YAML Validator FAQ
What kinds of YAML errors can it detect?
It catches parser errors such as bad indentation, invalid mappings, misplaced sequences, and malformed documents. In schema mode it also reports paths and values that do not satisfy the schema.
Can I validate YAML against a schema?
Yes. Switch to Schema mode and provide a JSON Schema. The schema input can be written in JSON or YAML, which is useful for manifests, config files, and API payloads.
