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.

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!"

SpreadsheetGear for .NET
So Much Easier

"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."

Performance, Flexibility
Priceless Support

"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."

Every Day that Goes By
I Am More Amazed

I must say that everyday that goes by I am more amazed with your component. It’s easy to use but still powerful. No more problems using Excel workbooks in the .NET environment.

You have spared me about 3 or 4 months of work with your excellent tool. I also must say that I’m using many other components from other companies and no one has proven to be as fast and effective as you in solving a support request.
