# Northstar CSV to JSON
1. Read the CSV.
2. Map `cust_id` to `customer.id`.
3. Map `gross_cents` to `invoice.gross.amount_cents`.
4. Emit one JSON file per invoice.
## Gotchas
- `gross_cents` can be negative for refunds.
- Empty `tax_code` means exempt, not unknown.
## Example
Input row:
```csv
cust_id,invoice_id,gross_cents,tax_code
C-1,INV-9,-1200,
```
Output shape:
```json
{"customer":{"id":"C-1"},"invoice":{"id":"INV-9","gross":{"amount_cents":-1200},"tax":{"status":"exempt"}}}
```
