Ever spent a whole evening copy-pasting invoice numbers into Excel by hand?
That was the actual brief on this one — a client was manually retyping vendor names, dates, and line items from PDF invoices into a spreadsheet every single week. Hours lost, and one typo away from a wrong total going out the door.
Built a Python script that reads the PDFs directly and skips the typing entirely.
Pulls vendor, invoice number, date, and every line item straight from the PDF's actual layout — real column positions, not just a text dump, so numbers land where they belong.
Handles multi-line invoices automatically, no manual splitting.
Outputs a clean Excel file — one sheet with invoice summaries, one with every line item, formatted and ready to hand to a bookkeeper.
Tested on 9 invoices, 26 line items, zero mismatches. Full script + sample invoices in the images.
Stuck retyping the same invoice fields every week? Send me one of your PDFs and I'll show you exactly what the parsed output looks like — free, no strings.
