Task-Based Workflow
Generate TypeScript Types from JSON Payloads
Turn sample JSON into reusable TypeScript interfaces so frontend and API code can stop guessing the response shape.
generate typescript from jsonjson to typescript interfacecreate ts types from api response
Why this workflow matters
When new endpoints ship, the frontend often starts by guessing the response shape. Generating types from real payloads gives you a faster and safer starting point than hand-writing interfaces from memory.
What success looks like
- Get usable TypeScript interfaces from live sample data.
- Reduce drift between API responses and frontend code.
- Use the generated types as a foundation for validation and mocks.
Best tools for this job
Recommended workflow
- 1
Paste a representative JSON payload into JSON to TypeScript.
- 2
Review the generated interfaces and add optional fields where the sample is incomplete.
- 3
Generate a schema or mock data next if you need stronger contracts or test fixtures.

Start with JSON в TypeScript
This workflow is anchored on JSON в TypeScript. Open it first, then move through the supporting steps only if the payload, request, or output still needs more work.
