For developers wiring up a new API who do not want to hand-type models. Paste a sample response and get a starter type for TypeScript, Go or Python that you can rename and refine.
Build industry projects on ByteLabs and add verified proof of your skills to your public profile.
You enter
{"id":1,"name":"CBC","tags":["dev","ops"]} with Target TypeScript
The tool shows
interface Root { id: number; name: string; tags: string[]; }
Yes. Each field name is capitalised so it is exported, and a json tag keeps the original key, for example Name string `json:"name"`.
Only top-level keys become fields. A nested object becomes Record<string, any> in TypeScript, map[string]interface{} in Go and dict in Python, so model it separately if you need full types.
No. The top level must be an object. Paste one element of the array and the tool will type its fields; array fields inside it are typed from their first item.
Yes. It is free, needs no sign-up and runs entirely in your browser, so what you type is not uploaded. You only sign in if you want to email a result to yourself or save it to your CareerByteCode profile.
