FAQ

What is YAML used for?

YAML (YAML Ain't Markup Language) is commonly used for configuration files, CI/CD pipelines, and data serialization. It emphasizes readability with indentation-based structure.

Can this tool convert JSON back to YAML?

Yes, the converter works in both directions — YAML to JSON and JSON to YAML — so you can transform between the two formats as needed.

Does it handle multi-document YAML files?

The tool processes single-document YAML by default. Multi-document YAML (separated by ---) may require splitting before conversion.
