Creating Custom Excel Add-Ins 45
Add-Ins Included with Excel
The following is a list of the add-ins included with Excel 2007. Some add-ins may not have been installed.
If you try to use one of these add-ins and it’s not installed, you receive a prompt asking whether you want
to install it.
n Analysis ToolPak: Statistical and engineering tools, plus new worksheet functions. Access the
Analysis ToolPak by choosing Formulas ➪ Solutions ➪ Data Analysis.
n Analysis ToolPak — VBA: VBA functions for the Analysis ToolPak. The functions in this add-in are
used by VBA programmers, and they are not accessible from Excel.
n Conditional Sum Wizard: Helps you to create formulas that add values based on a condition.
Access the Conditional Sum Wizard by choosing Formulas ➪ Solutions ➪ Conditional Sum.
n Euro Currency Tools: Tools for converting and formatting the euro currency. Access the Euro
Currency Tools by choosing Formulas ➪ Solutions ➪ Euro Conversion And Formulas ➪ Solutions ➪
Euro Formatting.
n Internet Assistant VBA: A tool for programmers that enables them to publish data to the Web. This
add-in is for VBA programmers and is not accessible from Excel.
n Lookup Wizard: Helps you to create formulas that look up data in a list. Access the Lookup wizard
by choosing Formulas ➪ Solutions ➪ Lookup.
n Solver Add-In: A tool that helps you to use a variety of numeric methods for equation solving and
optimization. Access the Solver add-in by choosing Formulas ➪ Solutions ➪ Solver.
In addition, you can download additional Excel add-ins from http://office.microsoft.com/.
The user interface for some Add-ins (including those included with Excel) may be integrated into the
Ribbon. For example, when you open the Analysis ToolPak add-in, you access these tools by choosing
Formulas ➪ Solutions ➪ Data Analysis.
If you open an add-in created in a previous version of Excel, any user interface modifications
made by the add-in will not appear as they were intended to appear. Rather, you must access
the user interface items (menus and toolbars) by choosing Add-Ins ➪ Menu Commands or Add-Ins ➪
Custom Toolbars. It’s likely that most add-in developers will create a new version of their add-in that uses the
new Ribbon interface.

Why Create Add-Ins?
Most Excel users have no need to create add-ins. But if you develop spreadsheets for others — or if you simply
want to get the most out of Excel — you may be interested in pursuing this topic further.
The following are several reasons why you may want to convert your Excel workbook application to an
add-in:
n
To avoid confusion. If an end user loads your application as an add-in, the file isn’t visible in the
Excel window — and, therefore, is less likely to confuse novice users or get in the way. Unlike a
hidden workbook, an add-in can’t be unhidden.
