title: Google Docs spreadsheet formula for most frequent keywords
body: <p>I wonder if there is a formula in Google Docs Spreadsheet which could identify and display (for example in column D) the most frequent (key)words in a spreadsheet? </p>
  
  <p>Let's say that I have a column (Column B) full of tweets (see example image) and I would like to find top keywords in the column B and display them in column D. Is there a way to do that?</p>
