PDF

Files in the same family (each month's price list from one supplier, for example) are compared against the column count and header text saved from the last download of that family.

The PDF is read in this browser and never uploaded. Checks only add warnings; no check edits a cell. Scanned pages go through OCR, which has no second source to confirm its numbers, so treat OCR numbers as unverified.
