Supplier price-list comparison

Find what changed.
Keep the source files intact.

Compare two lists from the same supplier by SKU. CSV or TSV, up to 50,000 rows and 10 MB per file. Files are processed on this device.

Try the example, or choose your old and new supplier files.

01 / OLD PRICE LISTChoose your previous file

02 / NEW PRICE LISTChoose the updated file

Both price columns use the same currency and unit / pack size. I am comparing the same supplier’s SKU system.

Use plain numbers with no currency symbols or thousands separators. Select each file’s decimal separator below its headers. Duplicate or blank SKUs stop the comparison.

SKU	Status	Old price	New price	Difference	Change

An added or removed SKU means it is absent from one file; it does not prove a product was introduced or discontinued. Percentage change from a zero old price is undefined. Reports are for review, not direct ERP import.
