## Frequently asked questions

### Should I generate code directly from JSON examples or from JSON Schema?

Use examples for quick model scaffolding. Use JSON Schema when multiple services or languages need a stable contract that can be regenerated and validated consistently.

### Can generated TypeScript types replace runtime validation?

No. TypeScript types help during development, but external input still needs runtime parsing. Convert JSON Schema to Zod when invalid data must be rejected at the boundary.

### Why include spreadsheet-to-schema in a typed code workflow?

Many ingestion projects start with XLSX columns instead of API schemas. Converting the sheet shape to JSON Schema gives the code generators a clearer contract.
