The Vendor Invoice Challenge

Every business faces these problems with vendor invoices:

  1. Inconsistent Column Names

    • "Product ID" vs "Item Code"
    • "Unit Price" vs "Rate"
    • "Quantity" vs "Qty" vs "Units"

  2. Different Data Formats

    • DD/MM/YYYY vs MM/DD/YYYY
    • Currencies: $, €, £, ¥
    • Units: pcs, pieces, units

  3. Varying Structures

    • Different column orders
    • Extra/missing columns
    • Merged cells
