Questions
How do I generate C# classes from JSON?
Paste your JSON into the input field and the tool will analyze the structure to produce C# classes with typed properties using { get; set; } accessors. Nested objects become separate named classes.
What C# types does the converter produce?
The converter maps JSON strings to string, integers to int, decimals to double, booleans to bool, and arrays to List<T>. Nested objects become their own classes with proper references.
Is the JSON to C# converter private and offline-capable?
Yes, all parsing runs in your browser. No JSON data leaves your machine, and the tool works offline once the page is loaded.
Can I use the generated C# classes with System.Text.Json or Newtonsoft.Json?
Yes, the generated classes work with both serialization libraries out of the box. Property names match JSON keys, so deserialization works without extra configuration.
How does JSON to C# handle null values?
Fields with null values in the JSON are typed as nullable (e.g., string?) in the generated C# class, so they can be safely deserialized from responses that include nulls.
