JSON to Go struct generator

Go’s static typing means you often need a struct that matches a piece of JSON, complete with the field tags that map JSON keys to struct fields. This generator turns JSON into idiomatic Go structs, adding the json struct tags, extracting nested types, and applying Go’s conventions — including capitalising acronyms like ID and URL correctly.

Those conventions are exactly what makes hand-writing Go structs tedious: exported fields must be capitalised, acronyms have a specific casing style, and nested objects become their own types. Generating the struct from real JSON gets all of that right and saves considerable typing.

It runs in your browser, so your data is not uploaded. Use it to model an API response in Go, generate structs for JSON config, or scaffold types from example data.
