Getting Started with XLL Plus

Thank you for downloading and installing XLL Plus. This page is here to help you get started creating Excel add-ins right away.

Install the XLL Plus toolkit

  • If you haven't already installed XLL Plus, download a trial version from XLL Plus Downloads.
  • You will need to have Visual Studio installed, including the C++ workload: Desktop development with C++. Use Visual Studio Installer to install it if you don't already have it. You will also need the ATL/MFC components: see HOW TO: Install the MFC individual component for details.
  • It's also a good idea to have Visual Studio's local help viewer selected: in Visual Studio 2019, click on the Help > Set Help Preference > Launch in Help Viewer menu item.

For more details, see XLL Plus Requirements.
