How to perform an action related to animating individual words from dynamic text

Hi
I'm trying to create a file that pulls groups of names from an Excel file (which I converted to JSON) and randomly scatters the group of names across the screen and every 5 seconds swaps and scatters the names of the next group of names.

My problem right now is that I don't understand how to do different animations for different words within a single text layer.

One solution I found is to make each word be on a separate layer using a script. The problem with this is that I have a file with 1325 names and I assume 1325 layers will crash my software.

If anyone knows how to do this correctly, I would be very grateful! 🙏

(The number of names in each round varies from 1 to 79)
