Compare CSV Files by Key Column
Choose the column that uniquely identifies each record. CatalogDiff matches records using that key instead of relying on row order, making comparisons safer when files have been sorted differently.
Open CatalogDiff and compare CSV filesHow it works
Load the previous and new CSV files, select a unique identifier column, optionally map product name, price and stock, and run the comparison. CatalogDiff can identify changed, new and removed records and export a difference report.
