Generate TypeScript interfaces from JSON
Paste a JSON object or API response and this JSON to TypeScript interface generator produces clean, ready-to-use interfacedefinitions. It walks nested objects, merges arrays of objects into a single interface, marks keys that aren't always present as optional, and unions mixed value types - so the output reflects your real data, not a guess.
Stop hand-writing types for every endpoint. Generate them in a second, rename the root interface to match your model, and paste the result straight into your codebase. The converter runs entirely in your browser - no uploads, no signup, and it works offline once loaded - so even private payloads stay on your machine.
