Your restored copy
Download restored product CSVThis product CSV preserves original values. Formula-like cells remain: spreadsheet software may interpret them. Import as text when opening it in a spreadsheet.
The source files were not overwritten. Review the recheck and Shopify import preview before importing.
Keep the current export and select your revised copy. We will run the checks again.

What this comparison does not cover
Image columns and image-only rows are excluded. Ambiguous option identities are flagged without guessing. The tool cannot see your live store, apps, inventory locations or external references. Missing CSV rows are not proof of product deletions.
Files stay in page memory and are cleared when you leave or refresh. Download your report before navigating away. Unknown fields are compared as text, not validated for import.
