Update Shopify products by Variant Barcodes

You can now update products with a file that identifies variants only by their barcodes, for example a supplier price list.

Fixes

#

• Variant Barcodes as the identifier - A products file without ID, Handle, Title, SKU, or Variant Barcode columns now finds each variant by its Variant Barcodes cell (Variant Barcodes).
• Any barcode matches - One barcode in the cell finds the variant through its primary barcode or any of its other barcodes.
• Several barcodes - A cell with several barcodes finds only the variant that has all of them.
• Shared barcodes - A barcode on variants of several products updates each of those products.
• Barcodes stay the same - The barcodes that identify a variant don’t change the variant’s barcodes.
