Generate Swift / Kotlin / Dart / Rust / Ruby / PHP / Scala types from JSON. Companion to JSON → Code.
Paste a JSON object, pick a target language (Swift, Kotlin, Dart, Rust, Ruby, PHP, Scala), enter a type / class name and click Generate. The tool infers field types from the values (boolean / integer / number / string) and emits an idiomatic struct / class / case class definition. Companion to “JSON to Code” which covers Java, Go, TS, Python, C# and SQL.
