PPTX
Microsoft PowerPoint Open XML Presentation
PPTX is Microsoft PowerPoint's default format since Office 2007, built on the same Office Open XML standard as DOCX and XLSX. Each presentation is a ZIP archive in which individual slides are stored as separate XML files, making the format easier to parse programmatically than the older binary PPT. It supports animations, embedded video, speaker notes, and slide masters.
