Need to create Cylindrical Datum Point(s) X,Y Feature in Creo using export from MathCAD

First I only have MathCad Express Prime 3.1

Created a spreadheet that gives me the X,Y points for my spiral

Copied the X,Y outputs from Excel into MathCAD

How do I create a Datum Point Feature using this X,Y output from MathCAD?  When I click on import while in the Datum Point (cylindrical) feature it only allows things like pts file.

'll keep plugging away at it but if anyone has ideas that would be excellent
