title: Find lines not starting with " in Notepad++
body: <p>I try to verify a CSV file where we had problems with line breaks.</p>
  
  <p>I want to find all lines not starting with a <code>"</code>.</p>
  
  <p>I am trying with <code>/!^"/gim</code> but the <code>!</code> negation is not working.</p>
  
  <p>How can I negate <code>/^"/gim</code> properly?</p>
