Book excerpt: For 40-some-odd years, the world of spreadsheets has been ruled by one king: Microsoft Excel. Sure, there were far away challengers that tried to overtake the beast--I'm looking at you, Lotus 1-2-3--but none have come close to dethroning the powerful tool...until Google Sheets. So what is Google Sheets? It's a cloud-based spreadsheet. Think Excel, but online. "But Excel is online," you say. Yes! But Google was there first, and really has the advantage over Excel in this arena. It's quicker and easier to use for collaboration. Google Sheets is also free; Excel has monthly/yearly subscriptions. If you'd like to get the most out of the software, then let's get started!
