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."

Fantastic -- From Excel To ASP.NET Dashboard in a Single Afternoon
"Fantastic evaluation -- I started with a customer’s Excel workbook with a dashboard containing variable cells and a chart. Using SpreadsheetGear, and your Dashboard from 1693 Analytics sample as a template, I created my own ASP.NET page to display our client’s dashboard, and update based on the selection of parameters which get plugged into the variable cells. And I got this working in a single afternoon."

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
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.

Thank you very much.

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.
