Microsoft sells Office under two models: Individuals and businesses can pay for the software license up front and own it forever (what the company calls the “perpetual” version of the suite), or they can purchase an Office 365 subscription, which means they have access to the software for only as long as they keep paying the subscription fee. And if you use spreadsheets, that generally means Excel.Įxcel is, of course, part of Microsoft’s Office suite of productivity tools. Microsoft Windows may get all the press coverage, but when you want to get real work done, you turn your attention to the applications that run on it.
