JSON to Dart Converter — Generate Dart Models Online
Convert a JSON object to a Dart class with fromJson, toJson, and null-safe fields.
🔒 All processing happens in your browser. Your JSON is never uploaded or sent to any server.
How to Use
- Paste a valid JSON object into the left pane. Supports JSON5 syntax (trailing commas, single quotes, comments).
- Optionally change the Root Class Name — this becomes the name of the outermost Dart class. Nested objects are named after their JSON key automatically.
- Click Convert to generate the Dart model. The Monaco editor on the right shows the result with syntax highlighting.
- Click Copy Result to copy the generated code to your clipboard, then paste it into your Dart project.
