JSON Model Generator

About JSON Model Generator

Generate TypeScript, C#, or Java models from a JSON sample. Create a starting point for typed API responses, then review field types and nullable values.

How to use this tool

Paste a representative JSON sample, choose TypeScript, C#, or Java, and generate a starting model.

What to know

Generated models reflect the sample, not a complete API contract. Review nullable fields, arrays, date strings, and naming conventions.
