Frequently Asked Questions
What is the difference between YAML and JSON?
JSON uses braces {} and brackets [] with quoted keys and values. YAML uses indentation and colons, with no quotes needed for strings. YAML supports comments (#), multi-line strings, and anchors/aliases. JSON is more portable for APIs; YAML is more readable for config files.
Can YAML represent all JSON data types?
Yes. YAML is a superset of JSON — valid JSON is also valid YAML. YAML additionally supports: comments, anchors (&alias) and aliases (*alias) for reuse, block scalars for multi-line strings, and more numeric formats.
What are YAML anchors and aliases?
Anchors (&name) mark a value for reuse; aliases (*name) reference it later: defaults: &defaults adapter: postgres. development: <<: *defaults database: dev_db. This reduces repetition in complex configs.
Why does my YAML fail to convert?
Common YAML errors: inconsistent indentation (must use spaces, never tabs), missing colon after key, incorrect string quoting (wrap strings with : or # in them), and duplicate keys (technically invalid but sometimes accepted).
What is YAML used for in software development?
YAML is the standard format for: GitHub Actions workflows (.yml), Kubernetes manifests, Docker Compose files, Ansible playbooks, Helm charts, Jekyll/Hugo config, and many CI/CD pipeline configurations.
