Microsoft Sparks Web Services for eBay:
"Specifically, developers may use Microsoft Office Excel 2003 spreadsheet and Microsoft Office FrontPage Web design applications to write services where eBay users could automate pricing and bid changes as needed. "

Participants in the eBay Developers Program can use XML application programming interfaces (APIs) with FrontPage 2003 to design Web sites that display custom information on items for sale on eBay. FrontPage 2003 includes Web design and maintenance tools and customized data views for listing multiple auction items.

With Excel 2003, users can: use XML to integrate with the eBay API to customize list views, graphs and charts; catalog bulk items online or offline; and submit item listings. The software allows eBay buyers and sellers to create a transaction record, analyze buying or selling history, and use automated uploading processes to submit listings.

To try the solution, users can download sample code with the eBay listing management capabilities within Microsoft Office from the eBay Developer site here.
