JSON to code

Paste JSON and get matching structs, classes or types for your language — Go, Python, C#, Java, Rust, Kotlin or Swift. Nesting, arrays and optional fields are handled. Nothing is uploaded.

Your JSON

Target language

Root type name

Options Inline single-use nested types

Generated code

Your JSON is parsed and converted entirely in your browser. Nothing is uploaded.

How it works

STEP 1

Paste your JSON

Drop in an API response or any JSON object. It is parsed right in your browser — nothing leaves your device.

STEP 2

Pick a language

Choose Go, Python, C#, Java, Rust, Kotlin or Swift. Names are turned into idiomatic types and nested objects become their own structs.

STEP 3

Copy or download

Copy the generated code with one click, or download it as a ready-to-use source file.
