## Overview

Convert raw JSON payloads into strongly-typed Go struct definitions instantly. This tool automatically infers nested types, exports fields using PascalCase, generates standard json struct tags, and supports optional omitempty tags to streamline your Go backend development.

## Inputs

- **JSON Input** (textarea): { "name": "Alice", "age": 30, "roles": \["admin", "user"\], "address": { "city": "Shanghai", "zip": "200000" } }
- **Root Type Name** (text): Root
- **Omit Empty Fields** (checkbox)

## When to use

- When designing Go backend APIs and needing to define Data Transfer Objects (DTOs) from JSON request or response payloads.
- When integrating with third-party REST APIs and needing to quickly scaffold Go structs to unmarshal JSON responses.
- When refactoring legacy configurations or mock data into native Go structures with proper struct tags.

## How it works

- Paste your raw JSON payload into the JSON Input text area.
- Specify a custom name for the Root Type Name and choose whether to enable the Omit Empty Fields option.
- The tool parses the JSON, infers the data types for nested objects and arrays, and generates the corresponding Go struct code.

## Use cases

- Generating Go struct models for incoming webhook payloads from services like Stripe or GitHub.
- Creating configuration structs in Go from existing JSON config files.
- Scaffolding API client response structures during integration testing.

## Frequently asked questions

### Does the tool support nested JSON objects?

Yes, nested objects are automatically extracted into separate, referenced Go structs or inline structures.

### How are JSON field names converted to Go struct fields?

Field names are converted to exported PascalCase to comply with Go visibility rules, while retaining the original names in the json tags.

### What does the Omit Empty Fields option do?

It appends ',omitempty' to the generated json struct tags, allowing Go's json package to skip empty or null fields during serialization.

### Can I customize the name of the main struct?

Yes, you can define a custom name in the Root Type Name field, which defaults to 'Root'.

### Does this tool run server-side?

No, the conversion is performed entirely in your browser, ensuring your JSON data remains private and secure.
