title: convert jupyter notebook saved as .HTML file back into .IPYNB
body: <p>Can I convert a Jupyter Notebook saved as <code>.HTML</code> file back into <code>.IPYNB</code> file? The  executable original notebooks were lost. The <code>nbconvert</code> docs don't have anything useful for this case. Currently I have to copy-paste bunch of cells into a new notebook, but this is very tedious and output cells will be lost this way.</p>

  <p>[EDIT]</p>
  
  <p>I found an interactive way to do this using BeautifulSoup:</p>
