Topic Under Construction
When you upload product updates, you can allow the descriptions in the spreadsheet to update the descriptions on existing parts.
When you answer yes to the prompt as shown in the image below, descriptions in the upload file overwrite the descriptions for existing products; if the description in the upload file for an existing product is blank, whatever is in the description for an existing product is left unaltered. If you answer no to the prompt, then descriptions for all existing products are unaltered regardless of the description data in the upload.
