Turn JSON into Go, Python, Rust, Kotlin & TypeScript data models.
Paste any JSON and instantly generate typed data models in Go structs, Python (Pydantic & dataclass), Rust (serde), Kotlin data classes, and TypeScript interfaces. Infers types, handles nested objects and arrays, marks optional fields, and adds the right serialization tags. Fully client-side.
This tool accelerates development by instantly transforming raw JSON payloads into strongly typed data models for multiple major programming languages. Operating entirely client-side, it processes data securely without server uploads, making it ideal for developers working with sensitive API responses. It handles nested structures, arrays, and optional fields automatically, eliminating manual struct and class writing.
Good to know: Extremely large JSON datasets may cause browser performance bottlenecks, in which case a command-line utility might be more appropriate.
Quickly convert JSON objects into typed data models for Go, Python, Rust, Kotlin, and TypeScript.
Paste your JSON into the input
Copy your raw JSON data and paste it into the main input field. The tool will automatically begin analyzing the structure and nested objects.
Select your target programming language
Choose your desired output format from the options, including Go structs, Python Pydantic models, Rust crates, or Kotlin data classes.
Review the generated data models
Inspect the inferred types, optional fields, and serialization tags generated in the output pane. The tool handles complex arrays and nested structures automatically.
Copy the code to your project
Click the copy button to grab the generated code and paste it directly into your application's source files. All processing happens locally in your browser.
