How to Use JSON to Go: Step by Step

Follow these simple steps to get started with JSON to Go:

Pro Tips for Using JSON to Go

Get the most out of JSON to Go with these expert tips:

Use omitempty for optional fields: Enable omitempty on fields that may not always be present. This produces cleaner JSON output and avoids sending zero values unnecessarily.

Check number types manually: Go uses float64 for all JSON numbers by default. If you need int or int64, adjust the types manually after generation.

Common Use Cases for JSON to Go

JSON to Go is perfect for:

  • Generating Go struct definitions from API response JSON for Go microservices
  • Creating data models from sample JSON for REST API client development
  • Rapid prototyping of Go type structures from configuration files and data schemas

    • Why Use JSON to Go Online?

    JSON to Go runs entirely in your browser — no downloads, no uploads, no sign-up required. Your data stays private on your device. It is free to use with no limitations, making it the perfect choice for developers, designers, and professionals who need quick, reliable results without compromising security.

    Frequently Asked Questions

    How does Go handle JSON numbers?▼

    Go unmarshals JSON numbers as float64 by default. For integer handling, use json.Number or custom unmarshalers. The generator uses float64 for all numbers.

    What is omitempty?▼

    omitempty omits the field from JSON serialization when its value is the zero value (empty string, 0, false, nil). Enable it for optional fields to produce cleaner JSON output.

    Is my data sent to a server?▼

    No. All conversion happens locally in your browser.
