JSON Deserialization: How to Deserialize JSON to Code
Learn how to deserialize JSON to objects, classes, and structs in C, C++, C#, Python, JavaScript, and Java with our free online tool.
Paste Your JSON Data
Enter your JSON data that you want to deserialize. The tool will analyze the structure and generate appropriate code for your selected programming language.
Example: Try This JSON Data
Copy and paste this JSON example to see how it works:
{ "name": "Alice Johnson", "age": 28, "email": "[email protected]", "isActive": true, "roles": [ "admin", "editor" ] }
Select Target Language
Choose your target programming language from the dropdown: C, C++, C#, Python, JavaScript, or Java. The tool will generate language-specific class/struct definitions with proper deserialization methods.
Click "Deserialize"
Our AI-powered backend converts the JSON into appropriate code structures for your selected language, including class definitions, properties, and deserialization logic.
Result: C# Class with Deserialization
public class User { public string Name { get; set; } public int Age { get; set; } public string Email { get; set; } public bool IsActive { get; set; } public List<string> Roles { get; set; } }

What is JSON Deserialization?
JSON deserialization is the process of converting JSON (JavaScript Object Notation) text into native data structures, objects, classes, or structs in programming languages. This transformation allows you to work with JSON data as first-class objects in your applications.
When you deserialize JSON, you're converting a text-based format into in-memory data structures that can be manipulated, processed, and used by your code. This is essential for consuming REST APIs, reading configuration files, processing data from databases, and inter-service communication.
Common use cases include: REST API responses, configuration file parsing, data interchange between microservices, web application data handling, and mobile app backends.
Frequently Asked Questions
What is JSON deserialization?
JSON deserialization converts JSON text into objects in your programming language. It's the reverse of JSON serialization. For example, converting JSON to a C# object or Python dictionary.
How do I deserialize JSON in C#?
Use JsonConvert.DeserializeObject<T>() from Newtonsoft.Json or JsonSerializer.Deserialize<T>() from System.Text.Json. Our tool generates the class definition for you.
What languages are supported?
We support C, C++, C#, Python, JavaScript, and Java. The tool automatically generates appropriate code structures for each language.
Is this tool free?
Yes! Completely free with no limits. Also try our JSON serialization and JSON formatter tools.
