When you upload a spreadsheet to edit products, you can now choose which column the editor uses to match rows to products or variants. Previously, the first column was always treated as the identifier, so anyone whose SKU, handle, or ID lived in a different column had to rearrange the file before uploading.
On the configure step, expand “Advanced Options” and use the new “Identifier column” dropdown to pick which column should be used to match rows. A magnifying glass icon then appears in that column’s top-left corner in the column-mapping table so it’s clear at a glance which column is doing the matching. The existing search-method dropdown below the column name still controls how the values are interpreted (Handle, SKU, Title, Variant ID, Product ID, Barcode, and so on).
Your choice is saved with the upload and used for both the product search and the edit itself, so you can upload spreadsheets in whatever shape your team already exports them in.
