Thank you for reaching out.
You may attach the excel file to your task or add them as a note/subtask.
it would be nice if I could streamline the task and subtask upload process to Weekplan. i.e. having a list of the tasks on an excel file and have them all as items in a subtask. is there a way I can do that?
Thank you for the response.
This option is not available through Week Plan but you can try using Zapier integration.
