JSON to Swift (Codable): Overview & Capabilities
A JSON to Swift converter generates typed Swift structs conforming to the `Codable` protocol with custom CodingKeys from JSON samples.
Generate Swift Codable structs with CodingKeys from JSON for iOS and macOS development. Engineered for developers, it runs 100% client-side in your browser for zero latency and complete privacy—no data is ever stored or transmitted across remote networks.

Key Capabilities
- Generates Swift structs conforming to Codable (Encodable & Decodable)
- Creates CodingKeys enum for custom property mapping
- Supports optional types for nullable fields
- Idiomatic camelCase property formatting
Frequently Asked Questions
Does it support Swift Codable protocol?
Yes, all generated structs conform to Codable for easy JSONDecoder usage.
How does it handle snake_case keys in Swift?
It converts them to camelCase properties and generates CodingKeys enum cases.
Can it handle optional fields?
Yes, nullable or optional fields are typed with question marks (e.g. String?).
