JSON to GraphQL Schema

Generate GraphQL schema type definitions from JSON data. Automatically infers types for strings, numbers, booleans, arrays, and nested objects with configurable root type name.

How to Use JSON to GraphQL Schema

The JSON to GraphQL Schema Generator converts JSON data into GraphQL type definitions automatically. Paste any JSON object and get corresponding GraphQL types with proper field types inferred — strings become String, integers become Int, decimals become Float, booleans become Boolean, arrays become list types, and nested objects generate their own named types. Set a custom root type name to match your schema conventions. Perfect for developers bootstrapping a GraphQL API from existing JSON data or REST responses.

Step-by-Step Instructions

  1. Optionally set a custom root type name
  2. Paste your JSON data into the input area
  3. View the generated GraphQL schema types in real-time
  4. Copy the schema to use in your GraphQL project
