What is PPTM?
PPTM files are PowerPoint presentations containing VBA (Visual Basic for Applications) macros - automated scripts that create interactive presentations, generate slides dynamically, respond to user interactions, and integrate external data. Based on Office Open XML format (ZIP container), PPTM is identical to PPTX but includes vbaProject.bin with executable macro code. Macros enable: auto-updating charts from Excel, interactive quiz presentations, custom navigation controls, and automated report generation.
PPTM is used in corporate training, educational software, interactive demonstrations, and automated reporting systems. Popular for creating quiz presentations with scoring, dashboard presentations that pull live data, and training modules with interactive elements. Common in sales presentations with custom product configurators and HR training with branching scenarios. PowerPoint displays security warnings when opening PPTM files. Can be saved as PPTX to remove macros. LibreOffice Impress supports PPTM with limited macro compatibility.
History
PPTM was introduced with Office 2007 as PowerPoint transitioned to Open XML format, clearly separating macro-enabled files for enhanced security.
