Creating Custom Excel Add-Ins 45
After you create the add-in, you need to install it:
1. Choose Office ➪ Excel Options ➪ Add-Ins.
2. Select Excel Add-Ins from the Manage drop-down list and click Go to display the Add-Ins
dialog box.
3. In the Add-Ins dialog box, click the Browse button to locate the XLAM file that you created,
which installs the add-in. The Add-Ins dialog box uses the descriptive title that you provided in
the Properties panel.
You can continue to modify the macros and UserForms in the XLAM version of your file.
Because the add-in doesn’t appear in the Excel window, you save your changes in the VB
Editor by choosing Office ➪ Save.
NOTE
An Add-In Example
This section discusses the steps to create a useful add-in from the change case.xlsm workbook I covered in
Chapter 41. This workbook contains a UserForm that displays options that change the text case of selected
cells (uppercase, lowercase, or proper case). Figure 45.2 shows the add-in in action.
FIGURE 45.2
This dialog box enables the user to change the case of text in the selected cells.
ON the CD-ROM
This file is available on the companion CD-ROM and is named change case.xlam. The file is
not locked, so you have full access to the VBA code and UserForm.
Setting up the workbook
This workbook contains one worksheet, which is empty. Although the worksheet is not used, it must be
present because every workbook must have at least one sheet.
Choose Insert ➪ Module in the VB Editor to insert a VBA module (named Module1). Choose Insert ➪
UserForm to insert a UserForm (named UserForm1).
