Which languages and frameworks do the code generators target?

TypeScript (interfaces/type aliases), Go (structs with json tags), Rust (structs with serde Serialize/Deserialize), Kotlin (data classes with @SerialName), Java (classes with Jackson @JsonProperty), and C# (PascalCase classes). Each emits code that works with the language's standard JSON libraries.

Can I generate types from an Excel sheet?

Yes. The XLSX-to-JSON-Schema tool infers a JSON Schema from worksheet headers and sample rows. You can then feed that schema into the code generators or the Zod converter.

Do the generators handle nested objects and arrays?

Yes. They recursively infer nested types, array element types, and nullable fields from the sample JSON, producing complete type definitions rather than flat top-level ones.

JSON to Typed Code Generators (TypeScript, Go, Rust, Kotlin, Java, C#)

Paste JSON and get ready-to-use types: TypeScript interfaces, Go structs, Rust structs with serde, Kotlin data classes, Java classes, C# classes, Zod schemas, and inferred JSON Schemas.

Overview

What this hub helps you accomplish

This hub is the fast path from raw JSON to typed code. Paste a sample payload and get idiomatic TypeScript interfaces, Go structs with json tags, Rust structs annotated for serde, Kotlin data classes, Java classes for Jackson, C# classes in PascalCase, or a Zod runtime schema. The schema tools round out the workflow: infer a JSON Schema from sample data or an Excel sheet, then feed it into the code generators or Zod converter. Every generator emits code that compiles and integrates with the language's standard JSON libraries, so you go from an API response or config file to production-ready types in seconds.
