I'm an electrical engineer that has become a proprietary cloud-tool admin. I occasionally use an LLM (chatGPT web) to write VBA code to do various API calls and transform excel/Jason/XML/CSV data from one format to another for various import/export tasks that would otherwise eat up my time.
I just use the chat, and copy/paste the code.
I spend an hour to meticulously describe the process I need the code to do, and then another hour or two testing, debugging and polishing, and get a result that would take me days to produce by myself. I then document the code (I try to use lots of sub-modules that can be reused) so that I can use the LLM less in the future.
I don't feel great about the environment impact, which is why I try to limit the usage, and do debugging and improvements by myself. I'm also trying to push management to invest in a lean LLM that runs on the companies servers. I'm also looking into getting a better PC privately, which I could also run a local LLM on and use for work.
