How to move data from Excel into To Do?

I'm an MS365 subscriber on Windows 10 (personal user, not business, so I hope I'm in the right place to post this).  I have learned to no longer trust apps by small developers with my to do list data, as I grow dependent on the app only to have development stop, or the app go away completely.

I figure MS will (hopefully) be around for a while, though, so I'm trying to keep my data in MS products.  I have all of my tasks in an Excel spreadsheet, with titles, start dates (I don't use due dates, only start), notes, and 3 different fields for prioritization (urgency, importance, and associated goal).

I'm reconsidering To Do as my "front end" (on an iOS phone).  But I need a way to get data at least in (out would be nice, too) from Excel.  I know I can paste multiple lines of text as individual tasks, but it seems like you can only move a task title that way.  Is there any kind of import, or connector, or VBA, or callback url schemes that can be used to bring data into To Do?
