JSON to Swift Codable Structs

Infer nested Swift structs and common value types from representative JSON without uploading the sample.

Representative JSON—

Generated starter code—

—JSON root

—Object keys

—Max depth

—Generated lines

ReadyThis is a starter model inferred from one sample, not a complete contract.

Review optional fields, unions, nullability, numeric precision, naming conventions, custom scalars, validation rules, and framework annotations against your real API/schema before using generated code in production.

How to use this JSON to Swift Codable Structs

Infer nested Swift structs and common value types from representative JSON without uploading the sample.

What the generated code means

The generator infers a starter model from the values present in one sample JSON document. It cannot discover fields missing from the sample, API business rules, every possible union, framework conventions, or future schema changes, so review the result before production use.
