I created a macOS Keynote slide presentation consisting of 153 photos. I exported the Keynote slides into Powerpoint for Mac 15.107.1 which created a Powerpoint presentation (ppsx file extension). I would like to convert the (ppsx to a pptx) file extension.

    The bot has the basic steps,but hasn't told you how to open the PPSX file. Double-clicking on it doesn't work, because it goes straight in to SlideShow mode. Instead, use the File>Open command in PowerPoint to open it in Normal (Edit) mode. Then save as PPTX.

    In PowerPoint, a .ppsx (PowerPoint Show) and a .pptx (PowerPoint Presentation) are the same file format internally; only the default opening behavior differs. On macOS, convert it by saving a copy as .pptx:

    1. Open the .ppsx file in PowerPoint for Mac.
    2. Select File > Save As.
    3. In File Format, choose PowerPoint Presentation (.pptx).
    4. Choose a location and select Save.

    The new file will be a standard .pptx presentation that opens in Normal (editing) view.
