JSON To Go Struct
Infer a Go struct from a representative JSON object.
Infer a Go struct from JSON
Writing Go structs to match a JSON payload by hand is tedious and easy to get wrong. This tool infers a struct — fields, types, and JSON tags — from a representative JSON object, giving you a solid starting point to paste into your Go code.
It reads the shape and types of your sample and generates matching struct definitions, saving the repetitive typing and the guesswork around tags. Paste a JSON object, copy the generated struct, and adjust types as needed.
Private and instant
Everything runs locally in your browser using standard web APIs — nothing is uploaded, logged, or stored on any server — so the tool works offline, responds instantly, and keeps whatever you paste in on your own device. That makes it safe to use even for confidential, client, or internal data you would never send to an unknown website.
