Spot the two errors in AI-typed rows

Course outline

Quick check

Guess first, no penalty. An invoice written day first says 08/09/2025. What date is that?

Here are 5 rows from a stack of scanned invoices (bills from suppliers), as they appear on the originals. The source documents use DD/MM/YYYY: day, then month, then year.

RowInvoiceDateSupplierAmount

5INV-104601/10/2025Tailspin Toys$2,750.00

Row 4 is your guide to the date format: 22/09 must be 22 September, so the file uses day first. Below are the same rows as an AI typed them.

Question 1 of 3

Your UK supplier invoices show 07/04/2025 (day first). The AI-extracted sheet shows 04/07/2025 for that invoice, while the invoice number, supplier and amount all match the original. What happened and what do you do?
