#FAQ
How do I generate GraphQL types from JSON? ▾
Paste your JSON data into the input field and the tool will infer types and produce GraphQL type definitions. Nested objects become separate named types with proper field references.
What GraphQL types does the converter produce? ▾
The converter maps JSON strings to String, integers to Int, decimals to Float, booleans to Boolean, and arrays to list types like [String]. Nested objects become their own named GraphQL types.
