You can open Keynote presentations saved on your iPad, in iCloud Drive, on connected servers, in other third-party storage providers, and on an external storage device that’s connected to your iPad. You can open and edit Microsoft PowerPoint presentations (files with a .pptx or .ppt filename extension) in Keynote, then save them as Keynote or PowerPoint presentations.
Note: When you open a presentation saved in iCloud Drive, it’s automatically downloaded to your device.
