How to Convert JSON to Elixir Modules - Step by Step Guide

Step 1

Input Your JSON Data

Start by adding your JSON data that needs to be converted to Elixir modules and structs. The tool analyzes the structure to generate appropriate modules with pattern matching support.

Example: Try This JSON Data

Copy and paste this JSON example to see how it works: 🧪

{
  "userId": 12345,
  "username": "elixirdev",
  "email": "dev@elixir-lang.org",
  "isActive": true,
  "preferences": [
    "fault_tolerance",
    "concurrency",
    "pattern_matching"
  ],
  "profile": {
    "firstName": "Phoenix",
    "lastName": "Developer",
    "age": 29,
    "country": "Brazil"
  }
}
Step 2

Configure Elixir Options

Customize how your JSON is converted to Elixir modules and structs! ⚙️ Choose pattern matching and functional programming patterns.

•
Structs: Generate Elixir structs with pattern matching and immutable data
•
JSON libraries: Compatible with Poison and Jason for JSON encoding/decoding
•
Nested modules: Handle complex JSON hierarchies with nested Elixir modules
•
Type mapping: Automatic Elixir type mapping from JSON data types
Step 3

Get Generated Elixir Code

Watch the transformation! ✨ Your JSON structure becomes clean, functional Elixir modules ready for Phoenix applications.

Elixir Code Output

Your JSON becomes these Elixir modules:

defmodule Profile do
  defstruct [:first_name, :last_name, :age, :country]

  def from_json(json) do
    %__MODULE__{
      first_name: json["firstName"],
      last_name: json["lastName"],
      age: json["age"],
      country: json["country"]
    }
  end
end

defmodule Root do
  defstruct [:user_id, :username, :email, :is_active, :preferences, :profile]

  def from_json(json) do
    %__MODULE__{
      user_id: json["userId"],
      username: json["username"],
      email: json["email"],
      is_active: json["isActive"],
      preferences: json["preferences"],
      profile: Profile.from_json(json["profile"])
    }
  end
end
Step 4

Copy or Download Elixir Code

Perfect! Now you can use your Elixir modules in your Phoenix applications for JSON processing. 🚀

•
Copy to clipboard for immediate use in your Elixir projects
•
Download .ex files for integration into your Phoenix application
•
Use with frameworks like Phoenix and Plug
•
Elixir applications and distributed systems

What is JSON to Elixir Conversion? 🧪

JSON to Elixir conversion transforms JSON data structures into Elixir modules and structs with pattern matching support for functional programming and Phoenix applications. This process analyzes JSON structure and generates Elixir modules that can encode and decode JSON data, making it easy to work with APIs in Elixir applications.

The generated Elixir modules include defstruct definitions, from_json functions for data transformation, and compatibility with JSON libraries like Jason and Poison, enabling fault-tolerant JSON handling in concurrent Elixir applications.

Frequently Asked Questions

What Elixir features are generated for JSON handling?

The tool generates Elixir modules with defstruct definitions, from_json functions for data transformation, pattern matching support, and compatibility with JSON libraries like Jason and Poison for encoding/decoding.

Can I use the generated modules with Phoenix?

Absolutely! The generated Elixir modules work perfectly with Phoenix applications, LiveView, OTP systems, and GenServers. They integrate seamlessly with Phoenix controllers, contexts, and JSON API endpoints.

How are nested JSON objects handled in Elixir?

Nested JSON objects become separate Elixir modules with proper relationships. The tool creates a module hierarchy that mirrors your JSON structure, with parent modules containing structs that reference child module types.

What Elixir data types are used for JSON values?

JSON strings become Elixir strings, numbers become integers or floats, booleans become booleans, arrays become lists, and objects become custom structs. The tool intelligently maps JSON types to appropriate Elixir types.

Do the generated modules support pattern matching?

Yes! The structs support full Elixir pattern matching, allowing you to destructure data, match on specific values, and use guards in function definitions for robust data processing in concurrent applications.

Is the JSON to Elixir converter free to use?

Yes, completely free with no limitations on JSON complexity, module generation, or usage frequency. No registration required, and you can generate unlimited Elixir modules from JSON data at no cost.
