title: Regular expression for changing spaces to tabs in Notepad++
body: <p>I'm trying to use regular expression in Notepad++ to change spaces to tabs in something like this</p>
  
  <blockquote>
    <p>01 fsdfsd</p>
    
    <p>01 01 fsdfsd</p>
    
    <p>01 01* fsdfsd</p>
    
    <p>01 01 01 fsdfsd</p>
    
    <p>01 01 01* fsdfsd</p>
  </blockquote>
  
  <p>How can I keep spaces between numbers and change only the last space?</p>
  
  <p>Thanks.</p>
