YAML format guide and tools
YAML is a readable configuration format with features beyond JSON.
Before you convert
JSON output cannot retain comments or presentation style. Complex aliases, tags and ambiguous types can be rejected or normalized. Review resulting values before using a converted configuration.
Check each tool’s processing label: browser and server tools handle files differently.
