Excel Web Access is a Web Part. It can display all or part of an Excel workbook, and enables interaction with the workbook in a browser by using Dynamic Hierarchical Tag Markup Language (DHTML) and JavaScript. Because Excel Web Access is a Web Part, you can add it to a site page such as a team site, and then re-use on another page at any time with no need to download an ActiveX control to your computer. In addition, you can connect the Excel Web Access Web Part to other Web Parts, such as filters, charts, and lists.
