As an Excel developer I love using SpreadsheetGear. It makes my job much easier as compared to MS Excel or Open Office Calc. The interface is very user friendly and not so advanced that you need to have tons of experience in Excel to get the best out of this product. You need to know how to use an excel sheet before starting to use this software. Also the support from the programmers is very poor. They don't reply to emails and tickets. The only way to communicate with them is through ticket system. And tickets are very difficult to navigate. If your looking for a spreadsheet program then there are a lot better options than this one. Try it out first and see if you like it. I am solving many problems here at work. I can now build different types of reports which previously required me writing code to do manually. This saves us a lot of time and resources.
