What is it?

If you write add-ins for Excel in C++, then you should be using XLL+. The toolkit helps you with all aspects of creating and maintaining an Excel add-in. Here are just some of the features:

  • AppWizard creates complete Visual Studio projects, ready to compile and run.
  • XLL+ Function Wizard helps you write and maintain Excel add-in functions, and generates most of the code for you.

Why use it?

Many programmers who write add-in functions for Excel prefer to do so completely in C or C++ rather than in Visual Basic, for any number of good reasons, including speed, stability and skills. The Microsoft Excel SDK is the only means of doing this without writing Visual Basic code.

Programming with the Excel SDK is a tedious and error-prone task that requires specialised skills and experience. The XLL+ toolkit hides the complexity of the environment and allows programmers and designers to concentrate on their core skills, whether these be in financial modelling, in communications, in engineering or elsewhere.

  • XLL+ has been designed by programmers with many years of experience writing add-ins for Excel. The toolkit has been used in the development of high-performance Excel libraries for financial calculations, engineering simulations, historical analysis and data feeds.
  • XLL+ has been in use since June 1997 and is now in its 7th major commercial release.
  • XLL+ is used by Fortune 500 companies, investment banks and universities all over the world.
