Hey Product Hunt! We built JSONConvert because I was tired of manually writing TypeScript interfaces every time I got a new API response. The idea is simple, paste JSON, get typed code. It supports TypeScript, Zod, Pydantic, YAML, CSV, JSON Schema, and a few utility tools like JSON Diff and Base64 decode. Everything runs in your browser. No backend, no tracking, no data collection. You can literally disconnect from the internet after loading the page and it still works. Would love your feedback, what formats should I add next? Prisma, Go structs, and Rust serde are on the roadmap.
