Instantly convert JSON API responses into structurally perfect C# Classes.
Why Use This C# Generator?
Never fail a code review again. Our engine automatically transforms incoming `snake_case` JSON keys into strict, idiomatic C# `PascalCase` properties to keep your .NET codebase perfectly clean.
We do the heavy lifting for you. Every property is automatically decorated with `[JsonProperty("original_name")]` tags, ensuring perfect serialization with Newtonsoft.Json or System.Text.Json.
Standard parsers break on massive numbers. Our engine intelligently detects when a number exceeds the 32-bit limit (like Twitter or Discord IDs) and safely casts it to a `long` to prevent Overflow exceptions.
Dealing with complex data? Paste any deeply nested JSON payload, and we will recursively extract, name, and generate every required Sub-Class, properly formatting arrays as `List
If an API returns a key named `class`, `return`, or `public`, standard generators will output broken code. Our keyword guard detects C# reserved words and safely escapes them so your code compiles instantly.
Parsing proprietary enterprise data or secure internal APIs? Your JSON is strictly secure. The entire C# conversion engine runs locally in your browser, and your data is never sent to a server.
