title: Open xlsx with vim
body: <p>I'm frequently getting <code>.xslx</code> files and do not have the newest Excel to open.  Open Office takes too long to open them as does converting software for older Excel versions.</p>
  
  <p>So, I want to open the xlsx file using vim (or maybe notepad++).  However, apparently it is not stored as standard text, so trying to open it results in random characters.</p>
  
  <p>Is there some way I can get vim or Notepad++ (or some other text editor) to open an XLSX file?</p>
