ABOUT THIS TOOL

Generate C# DTOs from real payloads

DevPayload infers common primitive types and recursively generates child DTO classes instead of collapsing nested objects into generic object properties. You can also target a JSONPath when you only need a DTO for one branch of a larger response.

COMMON USES

Useful for everyday developer work

Create DTOs from API response samples.
Generate a focused DTO from a nested JSONPath.
Bootstrap integration models before manual refinement.

HOW IT WORKS

Use this tool in three steps

Paste your data.

PRIVACY

Local by default

This public tool runs in your browser. Its input is not written to the DevPayload database.

FAQ

Frequently asked questions

Are nested objects generated as classes?

Yes. Nested objects are recursively represented as generated DTO classes when their structure can be inferred.

Should I use generated DTOs without review?

Treat generated code as a strong starting point. Review nullability, naming and domain-specific types before production use.

Do I need an account?

No. Public deterministic tools work without signing in.
