Automate Task Rescheduling and Cleanup with Asana & n8n

What This Workflow Does

This workflow automatically finds all completed tasks assigned to a user in Asana that were completed today. It also checks if there are any open tasks with due dates in the past. Then, it reschedules those overdue tasks to today and deletes the completed tasks. This saves time by reducing manual work and keeps Asana projects clean every morning at 7 am.

Who Should Use This Workflow

This is for anyone using Asana who manages lots of tasks daily. If tasks pile up unfinished with old due dates or completed tasks clutter the workspace, this helps clean and update the task list automatically. Project managers or team leads can rely on this to save time and avoid missing deadlines.
