Maximize the value your users get out of the information in your Windows Forms application by making it portable with Microsoft Excel and many other popular spreadsheet applications. Now you can build your data-driven solutions on top of the Infragistics.Excel code library for C# and VB.NET developers, with the interoperability you need to both read and write .XLS, .XLSX* and .XLSM* files. Your users will appreciate the freedom of working with data in the best environment for the task, such as running "What If?" scenarios in Excel and then importing those calculations back into your application. Collaboration like this produces remarkable returns because we take care of the interoperability, and relieve you of having to build expensive spreadsheet capabilities on your own.
