Convert JSON to GraphQL Schema

Transitioning from REST to GraphQL or designing a modern GraphQL API is fast and seamless with our JSON to GraphQL Schema generator. Paste any sample JSON response and instantly generate strongly-typed GraphQL type definitions, input types, and boilerplate Query / Mutation operations.

The engine automatically maps scalar types (String, Int, Float, Boolean), detects identifier keys (id, uuid, *_id) to infer ID! scalars, and recursively structures nested objects and [Type!]! array fields.
