A few cases just recently:

Someone in the company manages a TON of questionnaires. They type the questions into the service, get the results. The results are in an CSV format or some shit. Then they need to manually copy them to Google Sheets and do some adjustments on them.

Took me about 30 minutes of wall clock time, maybe 5 minutes of my time to have an LLM write me a simple python script that uses the API in the questionnaire service to pull down the data and insert it into a new Google Sheet.

Saves the person a TON of time every day.

Second case was a person who had to do similar manual input to crappy Sheets daily, because that's what the next piece in the process can read.

This person has a bit of an engineer mindset and vibe-coded a web tool themselves that has a UI that lets them easily fill the same information but view it in a more user friendly way. Then it'll export it in a CSV/JSON format for the next step in the process.

None of these would've been granted the day(s) of engineering time before, now both were something that could be thrown together quickly over a coffee break or done by themselves over a weekend.
