SupplyDiff turns supplier spreadsheets into reviewable changes

Field notes

SupplyDiff performs the comparison locally in the browser rather than sending catalog files to a server, according to the page. Its matching rules cover case, spaces, slashes, and dashes in SKUs, while pack-size changes trigger unit-cost comparisons. The exported result preserves source rows alongside match method, confidence, and formula-safe cell values, giving purchasing staff an intermediate file to inspect before importing anything elsewhere.
