"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."

"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."

"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.”

“Thank you again for your brilliant product and fanatical support. We have never looked back since we discarded FarPoint’s Spread in favour of SpreadsheetGear."

"We started to use SpreadsheetGear for .NET almost two years ago when the performance of other controls was becoming problematic. We needed a control that could handle large workbooks with complex formulas to be able to apply Monte Carlo simulation to financial statements. Since that time SpreadsheetGear for .NET has become our tool of choice not only for the performance but also for the flexibility. But most of all, the technical support we receive from SpreadsheetGear LLC is priceless; it has always been fast and accurate with the vision to arrive at the desired solution."

Your support is like your product: Perfect!!!"

"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!"

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!!!"

"We integrated SpreadsheetGear for .NET with an existing application with about two days work and it reduced the time it takes to generate a critical daily report from 20 minutes to 4 seconds. Thanks for making my team look like miracle workers!"

“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!"

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.

Great job!!!

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.
