title: What is the best library in python to deal with excel files?
body: <p>I have big excel with lot of sheets and formulas interlinked within the sheets. I need to populate input in one sheet using the code and recalculate all the formulas to get my output from another sheet.</p>
  <p>I am able to do this with apache POI using Java but it is too slow in formula recalculation. Looking for libraries in Python to do the same.</p>
