One I have used for years is because one of our vendors doesn’t have an api and only allows 30 day timeframes for data downloads. So to get one year of data you have to download 12 reports manually, switching the dates, etc. or I open murgee, click f2, and wait 2 minutes.

In adtech a lot of people are very technically adept but never learned to code so tools like that can fill needs quite well. Even if a vendor has an api I’d have to get product to dedicate hours/etc etc, or I can write a little automation and skip the api.
