Spire.Office for .NET is a compilation of Enterprise-Level Office .NET components offered by E-iceblue. It includes Spire.Doc, Spire XLS, Spire.Presentation, Spire.PDF, Spire.DataExport, Spire.PDFViewer, Spire.DocViewer and Spire.BarCode.
As an independent Office .NET component, Spire.Office doesn't need Microsoft Office to be installed on neither the development nor target systems. In addition, it is a better alternative to MS Office Automation in terms of security, stability, scalability, speed, price and features.
Spire.Office for .NET can be linked into any type of a 32-bit or 64-bit .NET application including ASP.NET, Web Services and WinForms for .NET Framework version 2.0 to 4.5.
