ExcelPackage

ExcelPackage is open-source software that provides server-side generation of Microsoft Excel 2007 spreadsheets. It is a set of classes and wrappers around the .NET 3.0 [http://msdn2.microsoft.com/en-us/library/system.io.packaging.aspx System.IO.Packaging API] and the new Office Open XML file format. It extracts away the complexity of dealing with the individual XML components making it real easy to create sophisticated spreadsheets on the server. Microsoft Office need not be installed.
