title: Remove multiple commas at the end of lines using Notepad++ regex replace
body: <p>I have a text below with data in a CSV file</p>
  
  <pre><code>2,3
  4,5
  6,7
  </code></pre>
  
  <p>When I save an open this in notepad++, it has extra commas like</p>
  
  <pre><code>2,3,,,,
  4,5,,
  6,7,,,,,
  </code></pre>
  
  <p>like you see, there are variable number of leading commas,</p>
  
  <p>I tried a regex match using:</p>
  
  <pre><code>/,{2,}/ 
  </code></pre>
  
  <p>I have selected the <strong>regular expressions</strong> combo-box from the search mode in <code>ctrl + H</code> Replace box.</p>
  
  <p>For some reason this is not working. What do I need to do to match multiple comma and not get rid of single comma?</p>
  
  <p>Is there a better way to get this done in notepad++?</p>
