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."
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.
