Are their ways to systematically split a single comma separated tag?

Hi,

As per topic, say I have ~100 Time Entries, each has a single tag that is a single comma-separated string, for example, “swimming,working,gaming” or “gaming,transporting”. Are there ways to bulk convert all these tags for all Time Entries into comma separated ones, so that the first time entry would have tags of “swimming”, “working”, “gaming” for example?

Much thanks!
