Excellent service and excellent products. They were extremely helpful and responsive during the GroupDocs.Viewer for .NET implementation process, can't recommend them highly enough.Martin Lasarga | Axentria ECM by G.S.I

Integrating GroupDocs.Viewer for Cloud API was simple with their fantastic Ruby SDK. There aren't that many companies out there who are willing to work with us on what we want. It's a great partnership.Margot Baill | Product Development Director at Hireology

After implementing and using GroupDocs.Viewer for .NET in the project it looks to be working very well. I have tested with a lot of documents and so far so good. Everything I've thrown at it renders nicely and looks just as good as it would in a PDF viewer or MS Word.Mats Oustad | Partner at Novanet AS
