About JSON to Code Converter

The JSON to Code Converter automates the creation of data models/classes from raw JSON data. Instead of manually writing boilerplate code for your API responses, generate it instantly for multiple programming languages.

How to Use?

  • Paste your JSON object into the left panel.
  • Select your target language (Java, Python, TypeScript, Go).
  • The corresponding class or struct definition appears in the right panel.
  • Copy the code into your application.

Features

  • Supports Java, Python (Pydantic/Dataclasses), TypeScript (Interfaces), and Go (Structs).
  • Infers data types (string, int, boolean, arrays).
  • Handles nested objects by creating separate classes/structs.

FAQ

Why use this tool?

It saves significant development time by eliminating repetitive typing and reducing errors when creating data transfer objects (DTOs) from API responses.

How accurate is the type inference?

The tool analyzes the values in your JSON. If a field is `null` or an empty array, it might default to a generic type (like `Object` or `any`). Providing a populated JSON sample gives the best results.
