Frequently Asked Questions

How does JSON to C# conversion work?

The tool parses your JSON, analyzes data types and structure, then generates C# classes with proper type mappings. Nested objects become separate classes, arrays become List<T>, and nullable types are inferred.

Does it support Newtonsoft.Json and System.Text.Json?

Yes. Select Newtonsoft.Json to add [JsonProperty] attributes, or System.Text.Json to add [JsonPropertyName] attributes automatically.

Can I generate records instead of classes?

Yes. Choose "record" style to generate C# record types instead of traditional classes.

Is my data secure?

Yes. All conversion happens in your browser. No JSON data is sent to any server.

Can I download the generated code?

Yes. Click Download to save the output as a .cs file ready for your project.
