Shape in Illustrator so it can be editable in PowerPoint

• Save your shape from Illustrator as .EMF file.

• Go to PowerPoint -> Insert a picture -> select your .emf file and click open.

• At this point it will act as a picture. You will have to right click the shape -> Group -> Ungroup.
• A prompt will appear asking you if you want to convert it. Click yes and after Ungroup it one more time.
• You will see that the shape has a transparent shape/background. Delete that and group the elements again (if there are more than one).

Done!
