Free Software that I rely on. One per day.
Day 22:
LibreOffice Calc
Behind the scenes, I have found a lot of uses for Calc spreadsheets (which I refer to as my "odious spreadsheets", because they're in "ODS" format).
In the screencap below from a doc, I was using it to establish the finishing state of various 3D assets.
I also use it every year for accounting for income taxes.
