There are several options for importing PowerPoint files into ProPresenter, anywhere from importing it natively for keeping the animations and transitions to importing the text and graphics to be able to edit the slides inside of ProPresenter.
It is important to note that ProPresenter cannot read PowerPoint files directly; all ProPresenter can do is ask PowerPoint to open the file and send the information to ProPresenter. Because of this, PowerPoint must be installed on your computer for any of these options to work. See this article for information on which versions of PowerPoint are supported by your version of ProPresenter.

To import a PowerPoint file, in the top left click on File > Import > Import PowerPoint. From here you will be able to select which file you want to import, as well as how you would like to import it. Note that on the Mac there is an alternate method of importing a PowerPoint file which will be covered below.
Import Native PowerPoint Slides (Windows only)
Using this option, ProPresenter will create a Document which contains thumbnails for all of the slides in the PowerPoint file, however when you click on a slide in ProPresenter, it isn't ProPresenter showing the slide on the screen; instead, PowerPoint will open in the background and show the slide directly. This will mean that any animation or transitions on the slides will show on the screen (because PowerPoint is rendering the output), but you can still see the thumbnails inside of ProPresenter. Note that or this feature to work, you will need to first go to the Display tab in Preferences and uncheck Display at Topmost Window Layer.
Import All Slides as JPEG Images
This option will have each slide in the PowerPoint file flattened into a still image, and then imported into ProPresenter. This option is preferred for Announcement slides, sermon slides, or other times you want all of the formatting to be preserved from the PowerPoint file.
Import Text Objects as ProPresenter Slide Elements
This option will grab all of the text boxes (and their formatting) from the PowerPoint file and import it into ProPresenter. This option is preferable if you are importing text or lyrics into ProPresenter for editing later, or if you want to change the formatting of the text after you import it.
Import Text and Graphic Objects as ProPresenter Slide Elements
This option will grab all of the text boxes (and their formatting) as well as any graphic objects on the slides from the PowerPoint file and import it into ProPresenter. This option is preferable if your slides have graphic objects on them and you want to be able to edit the text. Note that using this option will not import background images.
Import into a Playlist (Mac only)
One final option for importing a PowerPoint file into ProPresenter would be to drag it from the Finder directly into a Library Playlist in the bottom left of ProPresenter. This will load the PowerPoint file as an "object" inside of the Playlist. You won't see previews of any of the slides, however when you get to that part of the service you will see a play button for the PowerPoint file. Clicking on the button will launch PowerPoint and will use PowerPoint to display the file. This will leave ProPresenter completely, but it will keep things like animations and transitions visible for the audience to see. Note that or this feature to work, you will need to first go to the Display tab in Preferences and uncheck Display at Topmost Window Layer.
