JSON to Go

Convert JSON objects and arrays into Go structs with inferred types, nested structs, and JSON tags.

JSON Input
Go Output
Go structs
package models

// Generated from JSON.
// Review interface{} fields and inferred types before using this model.

type Profile struct {
	Country string `json:country`
	Timezone interface{} `json:timezone`
}

type ProjectsItem struct {
	Name string `json:name`
	Stars int `json:stars`
}

type ProjectsItem2 struct {
	Name string `json:name`
	Stars int `json:stars`
}

type GeneratedModel struct {
	ID int `json:id`
	Name string `json:name`
	Email string `json:email`
	IsActive bool `json:isActive`
	Roles []string `json:roles`
	Profile Profile `json:profile`
	Projects []interface{} `json:projects`
}

Generation notes

  • • Nested JSON objects become separate Go structs.
  • • JSON arrays become Go slices with inferred element types.
  • • Arrays of objects are analyzed together so fields from every sample are preserved.
  • • JSON field names are preserved using struct tags.
  • • The pointer option applies to nested struct fields.
  • • Null-only fields and mixed-type arrays may require manual type adjustments.
  • • Go zero values are used for missing fields unless you use pointers or custom unmarshalling.

How to use JSON to Go

  1. 1Paste a valid JSON object or array.
  2. 2Set the root struct name and pointer preference.
  3. 3Copy or download the generated Go code.
