Introduction to CSV's and the Mass Create Tool
A very efficient way to quickly manipulate large amounts of inventory data is to use what is known as a Comma Separated Value (CSV) file. CSVs are really just data files that can be opened and edited using a spreadsheet program like Microsoft Excel. The information stored in these files can be uploaded into your Crystal Commerce admin through the Mass Create tool, and can make more complex and targeted changes to your inventory than batch updates.
The Crystal Commerce admin uses Product Name as the main "identifier" when making changes, which means that the Product Name must be spelled exactly right for any changes to be made to that product. Even one extra space or an un-capitalized letter in a Product Name will result in a mis-match, and that line of the CSV will be ignored. It is therefore easiest to start with a CSV that has been exported from our system, because it will already have all of the Product Names completed correctly. You can export a CSV of any search you can perform in the Inventory > Products tab by clicking the “Export to CSV” button instead of the “Search” button. These exports can be downloaded from the Notifications > Generated Reports area of the admin.
