To create an outline which PowerPoint will understand, create a list of slide titles separated by a blank entry. 'Promote' each slide title and add the detail at lower level(s)
At the top level, select all the slide titles and blank entries. Then Write to a file with 'Use tabs instead and 'Only output selected entries' selected.
Open PowerPoint and choose File open, Files of type "All outlines", and point at the file you just created.
