Two things that look identical on screen
What a spreadsheet actually is
A spreadsheet is a grid of cells. Each cell holds a value, and its meaning is supplied entirely by the human reading it. Nothing in the file knows that column D is a phone number, or that row 47 is the same person as row 312. It stores whatever someone last typed, and nothing else.
What a CRM database actually is
A CRM database is a set of typed records that know about each other. A contact belongs to a company, a deal belongs to a contact and an owner, and every call and message belongs to the deal. Each field has a type, each edit is written to a history log, and each record carries a stage that software can act on.
