title: Add formatting to Excel formula of nested functions
body: <p>I have the following formula: <code>=ROUND(CONVERT(D157,"mi","km"),0)&amp;"kms"</code></p>
  
  <p>When the resulting number displays, it does so without "thousands" commas: ie - <code>3015kms</code>.</p>
  
  <p>I'm sure I need to use some sort of <code>TEXT</code> function with <code>#</code>s, <code>0</code>s and commas, but can't work out how to nest them successfully.</p>
