## About
Upload or paste last month's and this month's supplier price list as CSV. The comparator matches products by code or name, then lists every price increase and decrease with the percentage change, products that are new or have disappeared, and changes in pack quantity. Download the changes as a CSV to send to your supplier or your buyer. Your files are read in your browser and never uploaded.
