title: Converting .pdf files to excel (.xls)
body: <p>A friend of mine doing an internship asked me 2 hours ago if I could help him avoid to do manually 462 pdf file to .xls using free online soft.</p>
  
  <p>I thought of a shell script using <code>unoconv</code>, but I didn't find out how to use it properly, and I am not sure if <code>unoconv</code> can solve this problem since it mainly converts file to pdf, not the reverse thing.</p>
