fill lines of data based on other data structures: it can transform text quicker than you can write regex and i’ve never had it fail at thisI'm

not sure what you mean by that.

Not speaking for them, but I use LLMs for this. You have lines of repetitive code, and you realize you need to swap the order of things within each line. You could brute force it, or you could write a regex search/replace. Instead, you tell the LLM to do it and it saves a lot of time.

Swapping the order of things is just one example. It can change capitalization, insert values, or generate endless amounts of mock data.
