What our customers say

We had a very positive Flexcel talk in our meeting yesterday. Dave Martel was very positive about the product; the support; speed to fix an issue. By doing the talk he realised improvements over the years and has an amazing success story from analysing a large number of human created spreadsheets (1000’s of spreadsheets with 1000’s of readings). The speed of analysis allowed them to refine and re-train the importer to deal with human vagaries (comments / colour etc).

I don't know if you get many complements but I am constantly impressed with your tools. We use many of them in every application developed for the company I work for and unlike many, you have exceeded my expectations in both the tool and documentation.

Finally, a chart control that hits the sweet spot! As a product, AdvChart has the right approach. It's still very simple to use, the price is perfect, the code is included and easy to modify to taste and things that would be hard to add later or by the user are already taken into account like multiple panes.

I am really impressed about your know-how around Excel's under the hood workings. I've been kicking the FlexCel API around a bit over the weekend and must say it is the best investment I made in a long time in both time and money! And the speed at which you guys respond is incredible !

It is easy to use and powerful. I use it in cosole vb.net apps focused on reporting and calculation and it is fast in generating files. The feature of reporting by tags or "direct reporting" once known is a fundamental shortcut in report creation. Not only it is fast, but also powerful and I can say this because I use it integrated with sql server: download data from sql, apply complex calculation by an excel template hand-defined in Excel, convert to values and upload back to sql server. Size of this is about 60K rows X 70 columns X 6 (separate files). It works, obviously it consumes almost all the available 4 gb ram but it works even in 32bit mode. When I use Flexcel I feel myself as I was driving a powerful sport car. Thank you very much.
