Code Generators

Turn one format of code into another in a single paste, without opening an IDE or installing a converter. The JSON converters take a sample object and generate the matching type in your language of choice: TypeScript interfaces, Go structs, Python dataclasses and Pydantic models, Java classes, C# classes, Kotlin data classes, Swift structs, Rust structs, Dart and PHP classes, Zod schemas, JSON Schema, and SQL CREATE TABLE statements. The cURL converters take a request copied from a browser or API tool and rewrite it as code you can run: JavaScript fetch, Axios, Python requests, PHP cURL, Go net/http, Node.js http, Java HttpClient, C# HttpClient, PowerShell, and plain wget. Both sets keep the structure of your input intact, so the generated code is a starting point you can paste straight into a project and adjust. They are built for the moments developers hit daily — scaffolding types from an API response, or turning a curl command from documentation into working code in a real language. Everything runs entirely in your browser, so the payloads and endpoints you paste in never leave your machine, and there is no sign-up or per-use limit.
