Convert JSON to C# Classes

Generating C# properties by hand is a massive waste of developer time. Our JSON to C# generator builds perfectly formatted classes compatible with .NET Core and .NET 8. It leverages the native [JsonPropertyName] attributes from System.Text.Json.Serialization so your deserialization works securely out-of-the-box.

It automatically handles nested arrays, creating corresponding List structures, and maps standard numeric types securely to avoid serialization truncation errors.
