Import ClikUp or Excel task hierarchy into Smartsheet


Looking to migrate to SmartSheet from ClickUp. ClickUp supports as many levels of sub-tasks as you need:

Does anyone know of a direct integration from ClickUp to SmartSheet that preserves this? Zapier?

If not, is there a workaround that can pass through Excel first, somehow automatically format something like the above list into a parent-child structure, then pull into SmartSheet with hierarchy preserved?

I have thousands of items so manual is not desired.
