I set up Claude Cowork as a "Data Entry Clerk" — drag in a stack of invoices and receipts, say "log all of these," and it fills in your spreadsheet automatically.
Vendor, amount, date, category. Zero typing.
60 receipts logged in ~10 minutes. It even caught a $400 charge I got billed for twice.

Let me know if you set it up — curious what it catches in your books.
