title: Count number of cells with any value (string or number) in a column in Google Docs Spreadsheet
body: <p>I have several columns in  Google Spreadsheet. </p>
  
  <p>I would like to count how many cells have a value (number or string) and display that number at the top of the column.</p>
  
  <p><strong>For example:</strong></p>
  
  <p><hr>
  Hello
  <hr>
  World
  <hr>
  123
  <hr>
  Some string</p>
  
  <hr>
  
  <p>The above column would give me the answer of "4"</p>
  
  <p>I have not managed to find a formula that does this.</p>
