What is JSON to Scala Converter?
Need to generate Scala case classes from your JSON (JavaScript Object Notation) data? This tool does that instantly. Perfect for Scala developers working with Play Framework, Akka, or Spark who need to deserialize JSON into strongly-typed Scala objects. Generate case classes, Option types, and type definitions automatically.
According to Scala documentation, case classes are perfect for JSON processing. Our converter analyzes your JSON structure and generates proper Scala case classes. First, validate your JSON using our JSON Validator, then convert it to Scala. You can also format your JSON with our JSON Formatter first if needed.
Everything happens in your browser – your JSON never leaves your computer. Convert, download, and use your Scala case classes right away.
What Makes This Tool Different
Automatic Case Class Generation
We analyze your JSON structure and automatically generate Scala case classes. JSON objects become case classes, arrays become Seq[T] or List[T], everything gets proper Scala types.
Case Class Support
Generate Scala case classes for immutable, pattern-matchable data structures. Case classes automatically generate equals(), hashCode(), toString(), and copy() methods.
Option Types
Use Option[T] for nullable fields. Perfect for Scala's functional programming style and safe JSON decoding with proper error handling.
File Upload Support
Got a big file? Just upload it. Works great for converting those massive JSON configs or data files without copy-pasting.
Download Scala
One click to download your Scala file. Drop it into your Scala project and start using it. Perfect for Play Framework, Akka, or Spark applications.
Clean Code Output
The generated Scala code is clean and well-formatted. Case classes are properly named, fields are typed correctly, and the code follows Scala conventions.
How It Works
Paste or Upload JSON
Paste your JSON into the left editor, or click "Upload" to load a file. The JSON should be valid – use our JSON Validator first if you're not sure. You can also click "Sample" to see an example.
Configure Options
Set your case class name, package name, and choose whether to use case classes or Option types. These settings customize the generated Scala code to match your project's conventions.
Download or Copy
Click "Download" to save the Scala file, or "Copy" to copy it to your clipboard. The Scala code is ready to use in your project. Drop it into your Scala project and start using it.
When You'd Actually Use This
Play Framework
Generate Scala case classes from JSON API responses for Play Framework. Create models for REST APIs or JSON-based configurations. Perfect for Play's JSON processing needs.
Akka Applications
Create Scala case classes from JSON data for Akka applications. Generate data models for JSON-based message passing or configurations. Perfect for Akka's actor model.
Spark Applications
Generate Scala case classes from JSON data for Spark applications. Create data models for JSON-based data processing or configurations. Perfect for Spark's data processing needs.
Code Generation
Generate Scala code from JSON data structures. Perfect for creating data models, DTOs, or entity classes from JSON schemas or API responses.
Common Questions
Is my JSON data stored?
Nope. Everything happens right in your browser. Your JSON never leaves your computer – we don't even see it.
How are JSON objects handled?
JSON objects become Scala case classes. Properties become case class fields, and nested objects become nested case classes or references. Arrays become Seq[T] or List[T].
Can I use the generated Scala code?
Yes. The generated Scala code is valid and ready to use. Drop it into your Scala project and start using it. You may want to review and refine the case classes for your specific use case.
What about JSON serialization?
The generated Scala case classes work with Play JSON, Circe, or uPickle for JSON serialization. You may need to add implicit converters or codecs for custom serialization.
Does it work with large JSON files?
Yep. Since everything happens in your browser, it depends on your device. Small to medium JSON structures convert instantly. Really huge structures might take a few seconds.
What Scala version is supported?
The generated code works with Scala 2.11 and later. It uses standard Scala features and follows Scala conventions for maximum compatibility.
Other JSON Tools You Might Need
Conversion is just one JSON task. Here are other tools that work well together:
