title: How to replace only part of found text?
body: <p>I have a file with a some comma separated names and some comma separated account numbers.<br>
  Names will always be something like <code>Dow, John</code> and numbers like <code>012394,19862</code>.  </p>
  
  <p>Using <em>Notepad++</em>'s "Regex Find" feature, I'd like to replace commas between numbers with pipes <code>|</code>. </p>
  
  <p>Basically :</p>
  
  <pre><code>turn:  Dow,John      into:  Dow,John
         12345,09876          12345|09876
         13568,08642          13568|08642
  </code></pre>
  
  <p>I've been using <code>[0-9],</code> to <em>find</em> the commas, but I can't get it to properly leave the number's last digit and replace <em>just the comma</em>.</p>
  
  <p>Any ideas?</p>
