## What it is
A tool that instantly converts JSON into Go type (struct) definitions, available as a browser-based web tool and a Node.js script. It is a sister tool to curl-to-Go and also has a VS Code extension.

## Use cases
- convert a JSON payload into a Go struct
- generate Go type definitions from an API response
- paste JSON and get Go code instantly in the browser
- convert sample. to Go types from the command line
- quickly scaffold Go structs for working with JSON APIs

## When to choose
- you are writing Go code that consumes JSON and want to avoid hand-writing structs
- you want an instant, zero-install conversion in the browser
- you need a quick CLI conversion via Node.js from a file or stdin

## When to avoid
- you need guaranteed-correct output without review, since the tool makes assumptions about arrays of objects
- you need formatted, gofmt-ready output (you must run go fmt yourself)
- you are converting non-JSON data formats like YAML or XML
