Use case for Repeat Rows

Can you provide a use case for repeat row?
I am trying to think of how to use it but I see there hasn't been documentation published as of yet. When I attempted it I believe I tried on a text column so the message was a bit odd

A typical use case would be a table with a date range defined by two columns - Start Date and End Date. The goal would be to go from a date range per row to a single date per row in the ranges.

I’ve designed an example that illustrates the case I mentioned above. It requires the most recent build of the beta (.29 or later) as the action’s logic has changed.
