Microsoft Chooses SpreadsheetGear for .NET
"After carefully evaluating SpreadsheetGear, Excel Services, and other 3rd party options, we ultimately chose SpreadsheetGear for .NET because it is the best fit for MSN Money."
Chris Donohue Program Manager MSN Money
Spreadsheet Component Industry Veterans
"Our key developers have over fifty years of combined experience developing high performance commercially available spreadsheet technology which is used by most of the Fortune 500."
"We just wanted you to know how thrilled we are by the performance we are seeing with SpreadsheetGear for .NET. A 6,000 KB Excel workbook is loading into the WorkbookView control in less than a second. This is over 100 times faster than other controls we’ve tested. That difference makes it possible for us to develop and release a viable product with the Microsoft .NET Framework."
Amy Tate Chief .NET Architect Applied OLAP, Inc. Huntsville, Alabama
The More I Use It The More I Like It
"Thanks very much!
The more I understand and use SpreadsheetGear, the more I like it. Great job and excellent support."
Rob Stephens RGS Consulting Seattle, Washington
You Have an Excellent Product
"You have an excellent product. I've finished my testing and was able to rewrite a program using VB.NET and your control. I wrote the previous version 4 years ago using VB6 which employed the Excel COM object. The old program generated about 2100 excel sheets in 8 hours. With your control it now takes 7 minutes!
I also wrote a web form in ASP.NET VB using your control. This was also previously a VB6 / Excel app. This one went from 36 minutes to less than a minute.
I'm having no trouble getting this purchase approved!"
Mark Hitchcock Manager of Information Technology Administrative Concepts, Inc.
Hands Down the Most Intuitive and Easy to Use
"Thanks again for your prompt response, and I would just like to say that this is by far the best library that I have worked with. It is hands down the most intuitive and easy to use API that I have used to work with Excel files. Its performance is hard to beat as well.”
Levi Wilson Software Developer Press Ganey Associates South Bend, Indiana
Big Mistake Going With Competitor
I tried SpreadsheetGear a few months ago and decided to go with a competitor. Big mistake.
Code which opens two workbooks with a large number of formulas initially took over 3 minutes. With a lot of manipulation I got this down to 90 seconds.
SpreadsheetGear does it in 6 seconds!!!"
David Lees - Proprietor Compaid Computer Services Reading, England
Best Component Purchase for Many Years
“SpreadsheetGear for .NET provides a platform for spreadsheet web extension second to none. We were able to implement our custom formulas using the SpreadsheetGear engine with ease and these interact with the Excel functions seamlessly. The performance is superb and in many cases faster than in Excel which has been a pleasant surprise. The expertise of the development team is very apparent and we look forward to the new product enhancements coming down the line. From a return on investment perspective this has been our best component purchase for many years."
Mark Scanlon Managing Director XLCubed Ltd
Natural API, Blindingly Fast, Wow!
“Your interface-based approach is refreshing: the API is natural and the underlying code is blindingly fast for what it does.
Changing my Excel abstraction to use SpreadsheetGear brought a 2 month pull from 48 minutes (2880 seconds) to 12.7 seconds.

My Boss Thinks I'm a Genius
"Just wanted to give you a little good feedback on your product. I'm a programmer for a small company in Norway and we needed to create an Excel report for one of our customers. So I purchased a license for your wonderful product and it took me about 10 minutes to get the report from a DataTable into a finished Excel document!
My boss thinks I'm a genius, but hey; the credit should go to your product. At least half of it.
Hans Olav Stjernholm Chief Developer ZapDance as, Norway
Great Support Fantastic Performance
We finished our migration to SpreadsheetGear in only three weeks thanks to your great support and achieved a fantastic performance improvement. Our application used to spend 450 seconds waiting for Excel to load, calculate and save files. SpreadsheetGear does the same work in 24 seconds - 18 times faster!
Irakli Machabeli Och-Ziff Capital Management Group New York, NY
Special Product Great Job
We’ve been using SpreadsheetGear for 5 years. One of the things that makes this product special is that I really don’t have to think about it – I can spend my time worrying about the application that wraps it rather than the technology itself.
The vendor is great to work with too – technical questions are addressed quickly and accurately, without a lot of the refusal to admit problems that plagues other vendors.
Bill Wilson Development Manager Thomson Reuters
Excellent Product And Service
"Thank you for all your help during the trial period.
Your excellent product and service is what convinced us to buy this component."
I conducted a three month analysis comparing three top spreadsheet controls for .NET application developers: SpreadsheetGear, SyncFusion XlsIO, and ComponentOne Spread.NET. The definite winner was SpreadsheetGear, with ComponentOne Spread.NET in second. SpreadsheetGear provides the most Excel-like experience, is the most performant, and provides the most responsive and capable product support.
I build a reporting engine for my company and SpreadsheetGear made it awesome. Our customers have been very pleased. I wanted to share my extensive analysis with any other developers out there trying to find the right spreadsheet control for their .NET application.
Joseph Fluckiger Sr. Software Architect Thermo Fisher Scientific Austin, TX
