Office Excel 2007 delivers a new, results-oriented interface, PivotTable views that are easy to create and use, enhanced formula authoring, rich data visualization, and a much faster way to create professional-looking charts and tables. Share and manage spreadsheets that contain sensitive business information using Excel Services and Microsoft Office SharePoint Server 2007.
