Ask HN: What interesting things do you use spreadsheets for?

I don&#x27;t know if it&#x27;s interesting, but a while back I found that I was missing my old Casio databank watch, so I mocked one up in Excel, full color, CASIO logo included. Then I typed a whole schedule into it. That was fun, so I moved on to mocking up a pocket digital organizer (never got around to the alarm beep you coudln&#x27;t figure out how to turn off...). It was more than I could chew so that sheet is still a WIP somewhere.<p>(These days I&#x27;ve matured~ and do this kind of thing with textdraw so that aesthetics are less of a time suck)

I use them for forensic timeline analysis. Colour code certain results, and then you can sort them in various ways to tease out connections.

Habit tracking. With nicey colored cells for being a good boy.
