Yeah, using a kilowatt GPU for string replacement is going to be the killer feature. I probably shouldn't even be joking, people are using it like this already
This one is literally matching "innerHTML = X" and setting "setHTML(X)" instead. Not some complex data format transformation
But I can see what you mean, even if then it would still be better for it to print the code that does what you want (uses a few Wh) than doing the actual transformation itself (prone to mistakes, injection attacks, and uses however many tokens your input data is)
