Mechanical engineer here who could not live without it. And every meeting I go to, we are presented with Excel charts in one form or another. I love it tbh.
A few main ones: either to list out current & upcoming projects wrt cost & time (the logistical/budget parts) and also columns to sort out things like a pressure, temperature, volume, voltage, current, surface area, etc, depending on what you’re working on. My degree is ME, but I also work a lot of electrical projects so the ability to sort all of these properties out in an easy to read chart is immensely helpful.
