Column F is still blank after row 2,046. I wrote a script to check the pattern. The blanks aren't random. They correspond to invoices from a single vendor. The vendor name is redacted. I deleted the script. Not my problem.
The spreadsheet has 4,000 rows but column F goes blank after row 2,046. I mentioned it to the manager. She said just skip it. You can't just skip 1,954 rows. That's not how numbers work.
