JSON to Go Struct Converter

Transform arbitrary JSON payloads into idiomatic, production-ready Go struct type definitions with PascalCase initialisms and struct tags.

At a glance

JSON to Go Struct Converter is a free, client-side tool that converts JSON into idiomatic Go (Golang) structs online. It automatically detects RFC 3339 / ISO 8601 timestamps and outputs time.Time fields with import "time" declarations. Nothing is uploaded and no sign-up is needed — everything runs on your device.

Why Use This JSON to Go Struct Converter?

Idiomatic Go Acronym Formatting: Strictly adheres to official Go Code Review initialisms (ID, URL, API, IP, HTTP, UUID, SQL) in PascalCase field names.
Smart Type Inference: Infers exact Go types for integers (int, int64), floating-point numbers (float64), strings, booleans, and null pointers (*any).
ISO 8601 time.Time Detection: Automatically detects RFC 3339 / ISO 8601 timestamps and outputs time.Time fields with import "time" declarations.
Modular Struct Architecture: Choose between clean top-level decoupled structs or embedded inline struct definitions for nested objects and arrays.
Customizable Struct Tags: Configure standard json tags with optional omitempty, plus optional yaml and xml struct tags.
100% Client-Side Privacy: All parsing and code generation take place in your browser memory. Zero network payloads or telemetry.

How to Use JSON to Go Struct Converter

1

Paste Your JSON Payload

Paste arbitrary JSON data into the editor or pick one of the pre-loaded production example payloads.

2

Configure Struct Options

Set your desired root struct name, toggle separate nested structs, omitempty tags, or time.Time detection.

3

Copy or Download Go Code

Click 'Copy Code' to copy the aligned Go struct definitions to your clipboard or download them as a .go file.

Worked example: JSON to Go Struct Converter

Frequently Asked Questions

How does this tool convert JSON to Go structs?
The engine parses your JSON payload, infers Go data types (string, int, int64, float64, bool, slices, pointers), formats field names into idiomatic PascalCase with Go initialisms, generates aligned struct tags, and produces clean Golang type declarations.
Does it format Go initialisms correctly according to official conventions?
Yes. It adheres to the official Go Code Review Comments standard for common initialisms. Fields like user_id become UserID, api_url becomes APIURL, and remote_ip becomes RemoteIP.
How does it handle nested objects and arrays?
By default, nested objects and arrays of objects are extracted into separate top-level type definitions for clean modularity and reusability. You can also uncheck 'Separate Structs' to produce inline nested structs.
Is my JSON data kept private?
Yes, 100%. All processing runs locally in your browser memory using client-side JavaScript. No data is ever sent to any remote server or stored in any database.
