JSON to C# Converter
Free JSON to C# converter — generate C# classes from any JSON sample, in your browser. Powered by quicktype.
Paste your JSON on the left and the C# is produced instantly on the right — right in your browser. There’s no upload step: your data never leaves the page, which you can confirm from the Network panel or our privacy policy.
Type inference works best with a complete, representative JSON sample. Include every field you expect (and at least one element of each array) so the generated C# covers your real data.

Frequently asked questions
How do I convert JSON to C#?
Paste or type your JSON in the left editor (or use Sample / Upload / URL). The C# appears instantly on the right — copy or download it. Everything runs in your browser.
Is my data uploaded anywhere?
No. This converter runs entirely in your browser — your JSON is never sent to a server. You can verify it in the Network tab or in our Content-Security-Policy.
Does the generated C# handle nested objects and arrays?
Yes — types are inferred from your whole JSON sample, including nested objects and arrays. Paste a representative example with every field for best results.
