The bulk loader automates and streamlines the process of submitting multiple auctions. It allows sellers to upload many items at once by creating a comma separated values (CSV) file (with the file extension ".csv"), saving time and effort.

Using the bulk loader consists of three easy steps:

1. Create a file: This specially formatted CSV file contains details of each of your auctions.
2. Upload the file: This sends the CSV file from your computer to Yahoo! Auctions Express.
3. Submit auctions: When your file is uploaded to Yahoo!, you can review your auctions and then click "Submit" to make your auctions live on Yahoo!.
