JSON Code Generator: Models & Structs

Stop writing repetitive boilerplate code. Paste your JSON payload and instantly generate strongly-typed structs, classes, or interfaces for 11 different programming languages.

11 Supported Languages

Whether you are building a backend in Go, Java, Python, or Rust, or consuming an API in TypeScript, C#, or PHP, we've got you covered. Our code generator translates JSON types accurately.

Handles Nested Objects

Deeply nested JSON objects are automatically extracted and generated as separate structs or classes with proper references. No more manually flattening objects.

Popular Conversions

JSON to Go Struct: Automatically generates `json:"field_name"` tags for your Golang projects.
JSON to TypeScript Interface: Generates clean interfaces for your React, Angular, or Vue applications.
JSON to Java Class: Produces standard Java classes with private fields and standard getters/setters (coming soon).
JSON to Python Dataclass: Leverages modern Python 3 features with type hints for cleaner codebases.
JSON to Rust Struct: Adds `#[derive(Serialize, Deserialize)]` and Serde attributes instantly.

Completely Client-Side

Just like our formatter, the Code Generator runs entirely in your browser. This means you can paste sensitive API payloads containing PII without worrying about data leaks.
