I’ve just released a Microsoft Powerpoint Viewer that runs in IntelliJ IDEA and other JetBrains IDE’s such as Android Studio or PyCharm.
It can open pptx presentations, navigate the slides, copy text from the presentation or open the presentation in an office suite.
To run it, download the free Applet Runner plugin from JetBrains marketplace and execute the free Powerpoint Viewer applet located at https://www.japplis.com/applet-runner/office/powerpoint-viewer.html.
