JSON to Type/Model Compiler

Instantly compile raw JSON payloads into structured TypeScript interfaces, Go structs, Rust Serde models, Python classes, and SQL DDL.

What is Online JSON to Type/Model Compiler?

JSON to Type/Model Compiler is a developer utility that automates code generation by compiling raw JSON payloads into strongly-typed interfaces, models, and schemas for multiple backend and frontend environments.

Paste any valid JSON payload, load predefined sample datasets, and instantly retrieve corresponding structures in TypeScript, Go, Rust, Python, and SQL. The tool resolves nested objects and arrays dynamically into clean, decoupled model structures.

Features & Capabilities

  • Recursive JSON schema parsing and nesting resolution
  • Generates clean TypeScript types and interfaces
  • Generates Go structs with corresponding `json` tags
  • Generates Rust models with Serde serialization macros
  • Generates Python classes using Pydantic BaseModel or TypedDict schemas
  • Generates SQL CREATE TABLE schemas mapped to JSON datatypes
  • Client-side processing: your data is never uploaded to external servers

How to use Online JSON to Type/Model Compiler

  1. Paste or load your raw JSON payload into the input editor.
  2. Toggle configurations (e.g. optional fields, TypedDict, or Type Alias).
  3. Select your target language tab (TypeScript, Go, Rust, Python, SQL).
  4. Copy or download the compiled code instantly.

Use Cases

Invaluable for backend developers defining ORM structures, frontend developers mapping API payloads to TypeScript, and database engineers laying out database tables from logs.
