FAQ
What YAML syntax does this converter support?
The converter supports the full YAML 1.2 specification including scalars, sequences, mappings, anchors, aliases, multi-line strings, and multi-document files. It handles both block and flow styles.
How are YAML anchors and aliases handled in the JSON output?
Anchors and aliases are fully resolved before conversion. The referenced data is inlined into each alias location in the JSON output, producing a flat, self-contained JSON structure without any YAML-specific references.
Can I convert a YAML file with multiple documents?
Yes. Multi-document YAML files (separated by ---) are converted into a JSON array, where each document becomes one element. You can also choose to output only the first document if needed.
Is my YAML data uploaded to a server?
No. The conversion runs entirely in your browser using JavaScript. Your YAML content is never sent to any server, ensuring complete privacy for sensitive configuration files or secrets.
What is the difference between YAML and JSON?
YAML is a human-readable data serialization format commonly used for configuration files (Kubernetes, Docker, CI/CD pipelines). JSON is a lightweight data interchange format used by most APIs and web applications. YAML is a superset of JSON and supports comments and anchors, while JSON is more strict and universally supported by programming languages.
