JSON → Schema & Types

Paste a JSON sample and generate a JSON Schema, TypeScript interfaces, a Zod schema, Python Pydantic models, Go structs, or a SQL CREATE TABLE draft — recursively, with optional & nullable detection. Runs entirely in your browser.

Pair with the JSON / YAML Toolkit to format and validate, or the Diff Checker to compare two payloads. Nothing is uploaded — all generation happens locally.
