Grouping and Ungrouping Product in your Catalog
If you have products in separate product groups that should be in the same product group, you can use the bulk update tool to combine them. Since products are grouped together by Variation Grouping ID, the ID can be changed (or added) in order to put products in the same group.
The Bulk Upload Template can be downloaded by clicking on the Download Generic Third-Party Template Export on the Bulk Upload page
~ Or you can Export your existing data by clicking on the button marked "Full Catalog". The file may take a few time to export depending on the size of your catalog.
Open the downloaded file in Excel.
When editing. CSVs, Excel will automatically attempt to format the figures in your UPC column in Scientific Notation. To prevent errors, convert format to "NUMBER" or "TEXT" if there are any leading zeros
