Warning: The Batch Update Tool is powerful. It will allow you to make sweeping changes to your store's products and your eBay listings. Always preview your commands with the "Commit" option disabled first so that you are sure what they will do before you allow them to make changes to your store and eBay listings.
The Batch Update utility is available on the Tools Tab. It allows you to execute a series of simple, yet powerful, commands to update your eBay listings (and Zen Cart products).
As an example, suppose you added a number of listings to eBay then discovered that one of the Item Specifics you specified was incorrect. You could use the following set of commands to change the values of the "Brand" in the Item Specifics to "Company Name" in every listing where it is misspelled as "Copany Name":
WHERE ebay.itemspecifics INCLUDES 'Brand|Copany Name'
REMOVE 'Brand', 'Copany Name' FROM ebay.itemspecifics
ADD 'Brand', 'Company Name' TO ebay.itemspecifics
The WHERE Command defines the initial Working Set. The Working Set is the collection of products that following commands will operate on. Only products matching the expression in the WHERE Command will be included in the working set.
The REMOVE Command and ADD Command commands remove the invalid name and value from the list of Item Specifics then adds the correct name and value to the list for each product in the Working Set.
