Microsoft Office Excel is a powerful tool you can use to create and format spreadsheets, and analyze and share information to make more informed decisions. With the Microsoft Office Fluent user interface, rich data visualization, and PivotTable views, professional-looking charts are easier to create and use. Office Excel, combined with Excel Services, a new technology that will ship with Microsoft Office SharePoint Server, provides significant improvements for sharing data with greater security. You can share sensitive business information more broadly with enhanced security with your coworkers, customers, and business partners. By sharing a spreadsheet using Office Excel and Excel Services, you can navigate, sort, filter, input parameters, and interact with PivotTable views directly on the Web browser.
