Add-ins provide optional commands and features for Microsoft Excel. By default, add-ins are not immediately available in Excel, so you must first install and (in some cases) activate these add-ins so that you can use them.

Some add-ins are built in to Excel, such as Solver and the Analysis ToolPak. Other add-ins are available from the Download Center and must first be downloaded and installed. Finally, there are add-ins that are created by third parties, such as a programmer in your organization or a software solution provider. These can be Component Object Model (COM) add-ins, Visual Basic for Applications (VBA) add-ins, and DLL add-ins. These add-ins must also be installed to use them.

Most add-ins can be categorized into three different types:

  • Excel add-ins    These typically include Excel add-in (.xlam), Excel 97-2003 add-in (.xla), or DLL add-in (.xll) files or they are automation add-ins. Some Excel add-ins, such as Solver and the Analysis ToolPak, may be available after you install Excel or Microsoft Office. Typically, you only need to activate these add-ins to use them.

  • Downloadable add-ins    Additional add-ins for Excel can be downloaded and installed from Downloads at Office.com.

  • Custom add-ins    Developers and solution providers usually design custom Component Object Model (COM) add-ins, automation add-ins, VBA add-ins, and XLL add-ins. These must be installed for you to use them.

After you have installed or activated an add-in, the add-in and its commands may be available in one of the following locations:

  • Data tab. After you install and activate the Analysis ToolPak and Solver add-ins, the Data Analysis and Solver commands are available in the Analysis group.

  • Formulas tab. After you install and activate the Euro Currency Tools, the Euro Conversion and Euro Formatting commands are displayed in the Solutions group.

  • Add-Ins tab. Other add-ins may be added to the Add-Ins tab. This tab is added to the ribbon when you install and activate the first add-in that is shown in the Add-Ins tab. If you don't see the Add-Ins tab, you should exit and then restart Excel.

Other add-ins, such as the Get Started tab, are available in other places in Excel, such as a tab on the ribbon, or through macros or customized menus.

Important: If you are a software developer, you can use this procedure to install or remove an automation program before you design installation and removal programs for your add-in.
