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. Cheers!

SpreadsheetGear for .NET A Pleasure to Work With

SpreadsheetGear for .NET is truly a pleasure to work with. I was up and running within the first day. It is the best spreadsheet generator out on the market. Performance, Ease of Use, and Full Control of the generation process sold me. I no longer have to be concerned with memory leaks, hung processes, COM Interop and slow performance. Our users demand cosmetically appealing reports without additional work. I can build templates at will, with complete control to freeze panes, page setup, cell formats, etc., etc. The old days of pre-building templates are gone. I cannot think of anything this product cannot do.

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.

Reduced Time From 20 Minutes to 4 Seconds

Over 100 Times Faster Than Other Controls

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.

Excellent Product And Service

Thank you for all your help during the trial period. Your excellent product and service is what convinced us to buy this component.

You Have an 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!

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.

ASP.NET and SpreadsheetGear A Match Made in Heaven

ASP.NET and Microsoft Excel is a dangerous combination. ASP.NET and SpreadsheetGear is a match made in heaven.

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.

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.

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.

SpreadsheetGear 2009 In a League by Itself

SpreadsheetGear 2009 is Fantastic! I hate to think of NOT having SpreadsheetGear for even one day. These new capabilities just propelled this control way-way past any competition, of which you have none IMHO. As a programmer, I respect the amount of work, etc., that goes into a product that works well and as advertised. We have been using SpreadsheetGear since 2006 and it has saved us countless hours, headaches and $$$. We have had no recurring crashes since we removed all Office COM objects and replaced them with SpreadsheetGear. It seems that everything runs a lot smoother and much faster. SpreadsheetGear is in a league all by itself.

SpreadsheetGear ROCKS!!!!

We recently bought SpreadsheetGear for an Excel reporting project and have found it to be excellent! However, this week I have discovered that I can use SpreadsheetGear to open an Excel spreadsheet and interrogate it on the fly. This facility has literally saved me weeks of work. Hence I am just dropping you a quick email to say thank you very much. SpreadsheetGear ROCKS!!!!
Andrew Breward

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. Wow!
Dennis C. Wright, LLC

SpreadsheetGear Saved Hours of Development

Special Product Great Job

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!!!

Great Support Fantastic Performance

We finished our migration to SpreadsheetGear in only three weeks thanks to your great support and achieved a fantastic performance improvement. Our application used to spend 450 seconds waiting for Excel to load, calculate and save files. SpreadsheetGear does the same work in 24 seconds - 18 times faster!

Easy Conversion From Formula One

I am really glad to be using your SpreadsheetGear component. The conversion process from the Formula One spreadsheet component was as easy as it could be and your API is really well designed. Thank you very much.

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!!!
