What Is JSON to C#?
Convert JSON to C# classes instantly. Generate C# POCO classes with properties and attributes from JSON samples.
Key Features of JSON to C#
POCO Generation: Creates C# POCO (Plain Old CLR Object) classes with automatic properties and proper access modifiers.
JsonProperty Attributes: Optionally adds [JsonProperty("name")] attributes for JSON serialization compatibility with Newtonsoft.Json or System.Text.Json.
Nullable Reference Types: Supports C# 8.0+ nullable reference types with proper ? annotations on nullable fields.
Local Processing: All conversion happens locally — your data never leaves your browser.
Best Practices for JSON to C#
Follow these best practices to get optimal results:
Enable JsonProperty for snake_case APIs: If your API returns snake_case JSON (e.g., user_name), enable JsonProperty attributes to map to PascalCase C# property names correctly.
Use nullable reference types for safety: Enable C# nullable reference types to distinguish between required and optional fields, improving null safety in your codebase.
