title: Insert value in blank space using Excel formula
body: <p>We have a column of data that someone appears to have inadvertently deleted 0 from a string of  characters. e.g. ABCDEF 1 when the data should read ABCDEF01. </p>
  
  <p>The length of the data is each cell varies in length. How do i check for a space between a string and if it exists to insert the value 0?</p>
