Hey @Jeff_Wilson and @Eric_Higuchi! We will add this feature to our Guide article soon, but in the meantime, try following these steps:
- Access the project you want to add tasks to (in my example Project B)
- Click on the “…” dots menu next to this project
- Select “Add tasks via > CSV”
- Select your CSV file (in my example called "Project A) and click upload
- At that stage you will be required to map out the fields of your csv to fit the Asana project
- On my CSV file, subtasks are indicated in the “Parent task” column.
- So in Asana I’m associating with “Parent task” with “Subtask of”
- After importing my CSV, all subtasks are automatically showing under their respective parent task
Hope this helps!
