General Features

Reliable

This is the feature we care most about. If something doesn’t work, all other features are useless.

FlexCel for .NET is used daily by thousands of companies around the world, and we have a huge suite of automated tests that verify that it “just works”.

Fast

All code is optimized once and again to achieve the maximum possible performance. Because your users deserve fast applications.

Managed Code

FlexCel for .NET is written in 100% C# code without interops or p/invokes, for maximum portability, performance and security. There is no need to have Acrobat or Excel installed.

Multi platform

FlexCel for .NET Runs in Mono (Linux), .NET 64 bits, Xamarin.iOS, Xamarin.Android, Xamarin.Mac, Windows Phone and .NET CORE. You can use FlexCel on .NET 2.0, 3.5, 4.0 and 4.5 and there are optimizations for each version of the framework. Also Supports .NET Core. And everything is included in the same license!

Easy to deploy

In most cases there is only a single dll to deploy on your application, everything is there. There is no need for any third party dll or application, and of course you do not need Excel or Acrobat installed. Two small extra dlls add specific functionality for Winforms and ASP.NET.

Fully documented

FlexCel comes with a complete reference for every method (both integrated on Visual Studio Help and standalone), PDF files explaining the concepts, and more than 50 fully documented examples that you can browse and search from a “MainDemo” demo browser.

All Demos are available in both C# and Visual Basic.NET

Source code included

Because reading the source files and being able to debug them is invaluable when you have a problem, every license of FlexCel comes with full sources, at no added price.
