Winnovative Excel Library for .NET 7.1 Retail


The Winnovative Excel Library for .NET can be used in any type of .NET project, either ASP.NET and MVC web sites or Windows Forms and WPF applications, to enable your application to create new Excel documents from scratch or to edit existing Excel documents. The Winnovative Excel Library for .Net offers support both for the old Excel 97-2003 format (.xls) and for the new Excel 2007 and Excel 2010 (.xlsx) format.

The library is a .NET managed assembly and does not depend on Microsoft Office Excel. The library can also be used from ASP.NET applications running in more restrictive environments like servers where the trust level for the ASP.NET application was restricted to Medium Trust by the server administrator.

The integration is extremely easy and no additional installation is necessary in order to get started. The library is delivered as a strong named assembly that can be directly referenced by your project. The downloaded archive contains C# and VB.NET samples for ASP.NET and Windows Forms and the complete API documentation.

For a quick overview of the main capabilities of the library, a main features demo was made available online on our website.
The dynamic invoices demo shows how to dynamically create Excel invoices containing images, data tables and charts. The full C# and VB.NET source code of the online demo applications is available in the downloaded archive under the WnvExcelLib\Samples\AspNet folder.
