Best Practices for Using JSON to Go
Discover JSON to Go best practices. Learn pro tips, common mistakes to avoid, and expert advice for getting the most out of this free online tool.
What Is JSON to Go?
Convert JSON to Go struct types instantly. Generate Go structs with JSON tags from JSON samples for Go development.
Key Features of JSON to Go
Struct Generation: Creates Go struct types with properly typed fields and json struct tags.
JSON Tags: Generates `json:"field_name"` tags with optional omitempty for nullable fields.
Nested Struct Support: Creates separate type definitions for nested objects with proper Go naming conventions.
Type Inference: Maps JSON types to Go types: string, float64, bool, []interface{}, map[string]interface{}, and nested structs.
Local Processing: All conversion happens locally — your data never leaves your browser.
Best Practices for JSON to Go
Follow these best practices to get optimal results:
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.

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.
