Extract purchase order data from the file at [file URL], then generate an order confirmation PDF. Use the extract_document tool with these fields:

- customer_name (TEXT): Name of the customer or buying company
- po_number (TEXT): Purchase order number
- po_date (DATE): Date the PO was issued
- requested_delivery_date (DATE): Requested delivery date
- billing_address (TEXT): Customer billing address
- shipping_address (TEXT): Delivery address
- line_items (ARRAY): Each with product_sku (TEXT), product_name (TEXT), quantity (INTEGER), unit_price (CURRENCY_AMOUNT), line_total (CURRENCY_AMOUNT)
- currency (CURRENCY_CODE): Order currency
- po_total (CURRENCY_AMOUNT): Total order value

Then use the generate_document tool to create a PDF order confirmation from the extracted values.
