I have been privileged in my career to never need to parse Excel output but occasionally feed it input. Especially before Grafana was a household name.

Putting something out so manager stops asking you 20 questions about the data is a double edged sword though. Those people can hallucinate more than a pre-Covid AI engine. Grafana is just weird enough that people would rather consume a chart than try to make one, then you have some control over the acid trip.
