title: Build a random row picker that selects a row
body: <p>I have a Google Spreadsheets containing about 50 rows, each of which has values in the first four cells of the row. I'd like to build something where I can click a button (or a cell?) and have it return one of these rows, selected randomly. I had assumed that this would be fairly simple in Google Sheets, but lots of searching online hasn't yielded anything useful.</p>
  
  <p>I'm open to building something different (simple web app?) that will still do what I'm looking for.  </p>
  
  <p>Does anyone know how to do this, or even know some different language that I should be using as search terms?</p>
