JSON to Go Generator — Browser Type Tool

Developer

The JSON to Go generator is a browser-based developer tool that infers objects, arrays, nulls, numbers, and strings from a JSON sample and emits Go code.

JSON to Go

Runs in this browserInput is processed only in this browser. It is not sent to or stored on a server.

JSON input stays in this browser. Generated Go code is a sample-based draft; review optional fields, sanitized identifiers, semantic types such as dates or URLs, and API version differences before using it.

What is it

Use this tool to paste an API response or config JSON and quickly draft Go definitions. Keys are sanitized into language identifiers while original JSON keys are preserved through tags or rename metadata. Arrays are scanned across all items, and null values become nullable or union-style output where appropriate.

Go = render(infer(JSON.parse(sample)))

How to use

1Paste a JSON sample.
2Press Generate Go.
3Review sanitized identifiers and nullable fields.
4Copy the generated code and adjust it for your project.

FAQ

Is the JSON sample sent to a server?

No. This generator parses JSON and creates type code in your browser without sending input to a server.

Can I use the generated type directly in production?

Treat it as a draft. Review optional fields, API version differences, and semantic types such as dates or URLs before using it in a project.

How are array types inferred?

All array items are scanned to build a common type. Fields that appear only on some items are marked as optional or represented through nullable/union-style output.
