Frequently asked questions

Does this JSON to C# tool upload my data?

No. The converter runs in your browser. Do not paste secrets into any online tool, including this one.

Does it support nested JSON and arrays?

Yes. Nested objects become separate C# types, arrays become List<T>, and repeated shapes are de-duplicated.

Which serializer does it target?

The generated attributes target System.Text.Json and JsonPropertyName by default.
