JSON to Kotlin

Paste a JSON sample, such as an API response, and Bracely writes Kotlin data classes for kotlinx.serialization for it. Each object becomes a @Serializable data class, with @SerialName where a key needs it.

How to use it

  1. Paste a JSON sample.
  2. Set the root type name, for example Order.
  3. Copy the Kotlin code into your project.

What it does

Questions

How does it pick Kotlin types?
From the values in your sample: whole numbers, decimals, text, true/false, arrays and nested objects. When array items disagree, the field is made optional or widened.
Can I generate other languages?
Yes. Change Language to TypeScript, Go, Python, Java, C#, Rust, Kotlin, Swift, Dart, PHP, Zod, GraphQL or Protobuf.
Is my data uploaded?
No. Bracely runs entirely in your browser, so nothing you paste or open leaves your device.
