KDCalc converts Microsoft Excel spreadsheets into high-speed, light-weight calculation engines for the Java and .NET platforms. It consists of an Excel plug-in and a runtime calculation engine (~75KB in Java, ~170KB in .NET). KDCalc allows non-programers to build and test complex logic in Excel, then generate code for use in various applications. KDCalc supports over 180 Excel functions and has a simple API.

KDCalc can be used in any type of Java or .NET technology application. Use it in Java applets, servlets, and EJB(TM) servers or in .NET ASPX pages, web forms, windows forms, and console applications. In addition, the .NET version has a data adapter that easily integrates with .NET and third party controls and grids.
