I am still trying it out, but I have already written a Python script that creates a new
yWriter project from a CSV export file. It is free and open source and has an easy-to-use drag-and-drop interface. There is also an
Aeon 3 template based on Aeon's
Novel template that adds a "viewpoint" relationship to events and brings the required narrative numbering system.
To run aeon3yw, you need a Python installation preferably up-to-date.
