JSON to Dart
Generate Dart classes from JSON
The generator works best with JSON objects. If you paste a root array, the tool wraps it in an items field for the root model.
Tip
Paste a JSON object, set the root class name, and generate plain Dart models with fromJson and toJson methods.Flutter
Flutter Model Generation
Convert JSON into Dart models for cleaner app code.
This free online JSON to Dart converter is useful for Flutter developers who want faster model generation from API responses, config payloads, and structured app data.
Build API models faster
Generate Dart classes from JSON when you need a quick starting point for parsing API responses in Flutter or server-side Dart projects.
Reduce manual model writing
Instead of hand-writing every field, use a JSON to Dart generator to accelerate boilerplate creation and keep data structures easier to maintain.
Useful for Flutter workflows
This browser-based tool fits well into lightweight Flutter development tasks where you want model output quickly without leaving the browser.
JSON to Dart FAQ
Common questions about generating Dart classes online.
What is JSON to Dart used for?
A JSON to Dart converter helps turn structured JSON data into Dart model classes that are easier to use in Flutter and Dart applications.
Can I use this for Flutter API models?
Yes. This tool is designed for common Flutter and Dart API workflows where JSON responses need to become reusable model classes.
What if my JSON starts with an array?
If the root input is an array, the tool wraps it in an items field so a root model can still be generated more cleanly.
