Anecdote, but I needed some code to transform a couple of csv’s into one with some cells merged. I could have written the Python myself in about 45 minutes including the testing and spot checking.

Instead I described the csv’s that I had, the one I wanted, and asked for Python code to do it.

The code ChatGPT (v3) produced was flawless. I ran it on the data and spot checked it. The entire process took five minutes.
