Frequently Asked Questions
How does JSON to C# class generation work?
The tool analyzes your JSON data and generates C# classes with properly typed properties. Nested objects become separate class definitions with Pascal-cased property names.
Does it generate JsonProperty attributes?
Yes. Each property includes a [JsonProperty] attribute with the original JSON key name, ensuring correct serialization with Newtonsoft.Json or System.Text.Json.
How are nullable values handled?
JSON null values generate nullable reference types (object?) in C#. The converter preserves nullability information from your input data.
Is my data safe?
Yes! All processing happens entirely in your browser. Your JSON data is never sent to any server. No data is collected, stored, or transmitted.
What C# types are generated from JSON values?
JSON strings map to string, numbers to int or double, booleans to bool, null to object?, arrays to List<T>, and objects to named class types.
