Are you asking where the macros in a workbook are?
Well, you should know that Excel stores VBA stuff: macros, modules, user forms, etc. as well as spreadsheet data inside workbooks.
How does this work? Here’s a quick explanation…
To access your macros VBA code you need to open the workbook compartment that contains VBA data, this is the VBA interface.
There you will find the macros VBA code (procedures) in modules, see the picture below…

The fastest way to show the VBA interface is by using the shortcut ALT+F11, type it when you are in the workbook environment.
You can also use the Ribbon. Excel 2007/2010 brings the “Developer” tab hidden by default. Activate it this way…
If you are using Excel 2007 go to the Microsoft Office button>Excel Options>Popular>”Show Developer tab in the Ribbon”>OK
If you are using Excel 2010 go to the Microsoft Office button>Excel Options>Customize Ribbon, and then activate the “Developer” tab, see the picture below…
Once the Developer tab is shown in the Excel ribbon, activate it and click on the “Visual Basic” toolbar.
Another handy way to show the VBA editor is by right clicking over any sheet tab of your workbook and choosing “View code”.
You can also go directly to any given macro by going to the Ribbon: Developer>Code>Macros>Select your macro>Edit. See the picture below…
