Frequently Asked Questions
- Why does YAML fail so often?
- YAML is sensitive to indentation, colons, list markers and quotes. Tabs, missing spaces or unquoted special characters can break parsing.
- Can YAML and JSON be converted perfectly?
- Most normal objects and arrays convert well, but YAML comments, anchors and complex types may be lost when converted to JSON.
- Can it validate Kubernetes manifests?
- It can validate YAML syntax, but not Kubernetes field semantics. Use kubectl or a schema validator for resource-level validation.
