Saves you from hand-writing field names, types and json tags.

- Structs for nested objects
- Adds json tags for each field
- Infers string, int, float64, bool and slices
- Copy the result instantly
How to use
- 1Paste a representative JSON sample.
- 2Read the generated Go structs.
- 3Copy them into your project.
Examples
Object to struct
Input:
{"id":1,"name":"Ada"}Output:
type Root struct {
Id int `json:"id"`
Name string `json:"name"`
}Each key becomes an exported field with a json tag.
Decimal field
Input:
{"price":9.99}Output:
type Root struct {
Price float64 `json:"price"`
}A number with a decimal point is typed as float64.
Frequently asked questions
- How are numbers typed?
- Whole numbers become int and numbers with a decimal point become float64, based on the sample value.
- Are json tags included?
- Yes. Each field gets a json tag matching the original key name.
- Is my data uploaded?
- No. The generation runs entirely in your browser.
