How it works
Infer TypeScript types from sample JSON or CSV. Output is decision-support — review before you merge.
Step 1
Paste sample data
Drop a representative JSON object or CSV rows. Prefer real shapes over toy examples.
Step 2
Choose style
Interfaces, type aliases, or Zod schema — pick what your codebase already uses.
Step 3
Review flags
Read assumption notes and ambiguous-field flags. Human review still owns the merge.
Honesty: TypeGen does not guarantee 100% correctness and is not legal advice.
