Code Generation

Given a JSON sample, hand-writing matching types across every language you touch gets old fast. These tools generate TypeScript interfaces, Go structs, Python dataclasses/TypedDicts, Django models, SQL, Zod/Valibot schemas, and GraphQL types directly from JSON, plus mock datasets and HTML/SVG-to-JSX conversion for frontend work.

JSON to TypeScript

TypeScript

Generate robust TypeScript interfaces and types with optional/readonly support.

JSON to Go Struct

Go

Generate idiomatic Go structs with json tags and nested struct definitions.

JSON to Python

Python

Compile JSON to Python @dataclass, TypedDict, or valid literal source code.

JSON to Pydantic v2 Model

Pydantic

Generate Python Pydantic v2 and v1 BaseModel classes with snake_case Field aliases, ConfigDict, and UUID/datetime detection.

JSON to Rust Serde Struct

Rust

Generate idiomatic Rust structs with #[derive(Serialize, Deserialize)], #[serde(rename)], and raw keyword escaping.

JSON to Prisma Schema

Prisma

Infer Prisma ORM schema.prisma models from JSON with @id, @unique, @map snake_case, and foreign-key relations.

SQL to Drizzle ORM

Drizzle

Convert SQL CREATE TABLE DDL statements into TypeScript Drizzle ORM pgTable, mysqlTable, and sqliteTable schemas.

JSON to Django Model

Django

Draft clean models.Model schemas with field lengths and nullability hints.

JSON to SQL

SQL

Transform JSON filters to parameterized WHERE or objects to INSERT statements.

JSON to Zod & Valibot

Zod

Generate Zod v3 and Valibot validation schemas with type inference from JSON.

JSON to GraphQL Schema

GraphQL

Generate GraphQL types, query schemas, and mutation inputs from JSON payloads.

Mock Data & Schema Faker

Faker

Generate realistic mock datasets (Users, Products, Telemetry) in JSON, CSV, and SQL.

HTML to JSX / React

React/JSX

Convert raw HTML to clean React JSX/TSX with class to className, styles, and self-closing tags.

SVG to JSX / React

SVG

Convert raw SVG code to clean React JSX/TSX components with live vector preview and currentColor styling.
