Java .properties files use a flat key=value format where nested structure is expressed through dot-separated keys (e.g., database.host=localhost). Spring Boot, Quarkus, and many Java frameworks accept both YAML and .properties formats, but some tools and legacy systems only support .properties. This converter flattens a YAML hierarchy into the equivalent flat key=value pairs, handling nested objects, arrays (indexed askey.0=value), strings, numbers, and booleans.
