PPS to PPSM conversion is the process of transforming a PowerPoint Show file (PPS), which opens directly as a slideshow, into a macro-enabled PowerPoint Show (PPSM) that can include and run embedded VBA macros. This conversion preserves the slideshow format while enabling automated behaviors, interactivity, or custom scripting supported by PPSM files.
