What is the difference between JSON and YAML?

JSON uses braces and brackets with strict syntax rules. YAML uses indentation and is designed to be more human-readable. Both are data serialization formats, but YAML supports comments and multi-document files.

When should I use YAML instead of JSON?

Use YAML for configuration files (Docker Compose, Kubernetes, CI/CD pipelines) where readability and comments matter. Use JSON for APIs and data interchange where strict parsing and wide compatibility are important.

Does the converter support YAML comments?

YAML supports comments but JSON does not. When converting YAML to JSON, comments are removed since JSON has no comment syntax.

What happens with multi-document YAML files?

Multi-document YAML files (separated by ---) are supported. Each document is converted and the results are presented clearly.
