"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."

“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."

"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!"

“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.
Wow!"

"I have one big problem with Spreadsheetgear for .NET, my billable hours are going to go down because your product is so much easier to use than a web grid. Yikes!
I sure wish I had found your product a couple of years ago. And converting my webgrid code over to SpreadsheetGear for .NET is going very quickly because all of the logic is already coded and I just have to write to the spreadsheet.
I really like not having to insert columns and rows when I need them. I really like your product so far."
