“We are a company providing Enterprise Digital Pen & Paper Solutions. We use GemBox.Spreadsheet to provide comprehensive reports to clients showing Hand Written Recognition data extracted out of Digital Forms. GemBox.Spreadsheet is easy to use, very coherent in its features and best of all its hugely performant. We see no significant spikes in CPU or RAM when we run large reports and they run really, really fast.”

Marshall Brooke, Senior Technical Architect at Digital Field Solutions


“GemBox Technical Support is wonderful. They’re responsive and incredibly helpful by providing code snippets and examples. I’ve never had to go back to them twice for the same issue because the issue wasn’t addressed correctly. Congratulations on such a useful product and superior customer support!”

Aimee Stinson, .NET Specialist at Xperts, Inc.


“This is the ideal product for anyone looking to easily add spreadsheet generation to their application. Any developer or project manager considering implementing Excel automation needs to download the trial of GemBox.Spreadsheet.”

Nathan A. Baylor, Director of Information Technology at Avalon Risk Management, Inc.


“To say that I am happy with the GemBox.Document purchase is an understatement. Not only does it do what I had hoped it would, but it also does a lot more and I probably haven’t even touched the surface. I have also had the need to contact technical service twice, and both time they have gotten back to me in less than a day and solved my problem. I cannot speak highly enough of your product and customer service, and I am telling my developer friends all about it!”

Greg Harshman, Purchasing & Software Developer at PFB America Corp.


“Being able to include the product directly in my C# project from the NuGet Package Manager has made its installation incredibly easy. So far it has worked brilliantly with a very intuitive API and easy learning curve.”

Ryan Russell, Software Developer at Aventa Systems


“In a matter of a day or two I was able to create a formatted spreadsheet report that presented an exported data table. The spreadsheet report is client quality. The examples on the web site were a huge help! Every question I had was answered by an example and I just copied and refined the code to meet my specific needs.

GemBox.Spreadsheet is every bit as good as the GemBox.Document software I already have! I already have recommended GemBox software to a colleague.”

Bob Maguire, Owner of Genpres, Inc.


“I found your product to be very easy to download, install and use. It took me less than 30 minutes to install GemBox.Spreadsheet and write a C# test program. The API seems very intuitive.
I was also impressed by the speed of GemBox.Spreadsheet. I was able to write an Excel data file much, much faster than using Interop.”
