What is PPSX file format?

PPSX is a Microsoft PowerPoint Open XML Presentation file type. It is similar to PPTX, but differs in that it contains a single slide that is meant to be viewed as a slideshow. PPSX files are generally used when sharing a presentation with a large group of people, or when creating a presentation that is meant to be played on a projector or TV. The PPSX format is similar to a PPTX file but contains a slightly different format structure than a PPTX file.

The PPSX file format is based on XML, making it a more versatile format than the PPTX format. It is compatible with many versions of Microsoft PowerPoint, as well as Apple’s Keynote software. PPSX files can be opened on any platform that supports the Open XML Presentation format, and can be viewed on computers, TVs, or projectors.

PPSX files are a great option for those who want to share a presentation with a wide audience, such as those attending a webinar or virtual meeting. Since the PPSX format is based on XML, it can also be used for easy editing and versioning of presentations.
