JSON → Go Structs
JSONGenerate Go struct definitions from JSON with proper field names and json tags
Paste a JSON API response and get back a matching Go struct with properly PascalCased field names and `json:"..."` tags already wired up, saving the tedium of hand-writing a struct every time you integrate a new endpoint. Nested objects and arrays of objects generate their own nested struct types with sensibly singularized names rather than flattening everything to `interface{}`, though a null field or a genuinely mixed-type array does fall back to `interface{}` since there's no single concrete type to infer. Because JSON doesn't distinguish integers from floating-point numbers as cleanly as Go does, it's worth double-checking numeric field types in the generated struct rather than assuming the inference always guessed right. For the equivalent job targeting Python instead of Go, see JSON to Python.
How to use JSON → Go Structs
- 1.Paste a JSON API response to instantly generate a matching Go struct with properly cased field names and `json:` tags.
- 2.Use it when wiring up a new API client so you don't have to hand-write struct definitions field by field.
- 3.Paste nested JSON objects and arrays to get correctly nested struct types instead of flattening everything into `interface{}`.
