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.
