JSONGo Struct
JSON to Go Struct Generator
Generate Go struct definitions from JSON data. Paste an API response and get production-ready Go structs with proper json tags, PascalCase field names, and correct type mappings for strings, numbers, booleans, and nested objects.
Features
- Infers string, int, float64, bool types
- Nested objects become separate structs
- json struct tags with original field names
- PascalCase Go field naming convention
- Slice type inference for arrays
Frequently Asked Questions
Does the output include json tags?
Yes. Every field includes a json struct tag with the original JSON key name, so Go's encoding/json package can properly marshal and unmarshal the data.
How are nested objects handled?
Nested JSON objects become separate Go struct types. The parent struct references child structs by type name, following Go conventions for struct composition.
What Go types are inferred?
Strings become string, integers become int, decimals become float64, booleans become bool, null values become interface{}, and arrays become slices of the inferred item type.
