When you run a spreadsheet edit in the app there's an option to download a report of the rows in your spreadsheet that didn't match any products in Shopify. This can be helpful in identifying any Shopify products that are missing or mis-labled.
We've updated this unmatched rows report to include the column names from the original file. Previously the columns were numbered sequentially but now you'll see the actual names of the columns which should make it easier to identify the missing products.
