Hi @Anonymous,
Do you want to create a new task when a new row is added in an excel file?
Could you please share a bit more about your scenario?
Currently, there is no OOTB new row added trigger for Excel table, so we could not create a new task based on the new added row from the excel file.
As a workaround, I will suggest you add a field in your excel file to save the task id so that we could create a new task based on that if there is a task id existing in the excel file. If there is no task id in one row, you could create a new task.
