The macro recorder, used to automate frequent tasks, is not available in PowerPoint 2013 or newer versions. Instead, you can use Visual Basic for Applications (VBA) to create or edit macros. This includes editing those that were created in earlier versions of PowerPoint.
To create or edit a macro by using Visual Basic for Applications, do the following:
On the View tab, choose Macros.
In the Macro dialog box, type a name for the macro.
In the Macro in list, click the template or the presentation that you want to store the macro in.
In the Description box, type a description for the macro.
Click Create to open Visual Basic for Applications.
Important: This feature isn’t available in Office on a Windows RT PC. Want to see what version of Office you're using?
