From sample JSON to working types

Typesmith turns a sample payload into code you can use immediately. Inside VS Code, run Typesmith: Generate Interface from the Command Palette, paste JSON into the webview, choose TypeScript or Python, and generate a model without leaving the editor.

The extension keeps the workflow deliberately small: syntax highlighting makes the input and result easy to scan, while a clipboard action moves the generated code straight into the project.

A browser companion for more languages

Typesmith on the web carries the same idea into a standalone workspace and expands the output choices to JavaScript, Java, C#, C++, Go, and Rust. That makes the tool useful when a payload needs to become a model for another service, not only a TypeScript frontend.

Designed to stay in the flow

I built the extension to feel at home in VS Code: it opens as a focused webview, follows the editor's dark interface, and has no external setup. The result is a short path from an API response to a typed starting point, especially when exploring an unfamiliar endpoint or scaffolding a new integration.

Available in VS Code

The extension is available from the Visual Studio Marketplace. Its current generator focuses on TypeScript interfaces and Python classes; deeply nested mixed arrays and very large JSON objects remain areas for further improvement.
