title: A whole sheet into a pandas dataframe with xlwings
body: <p>Thanks to pandas, we could read a whole sheet into a data frame with the &quot;read_excel&quot; function.</p>
  <p>I would like to use the same method using xlwings. In fact, my Workbook is already open and I don't want to use read_excel function (witch will take too long to execute by the way) but use the power of xlwings to save into a dataframe a whole sheet.</p>
  <p>In fact with xlwings we could save a range into a dataframe. That mean I have to known the range size. But I guess there is a better (and quicker!) way to do that, isn't it?</p>
  <p>Do you have some ideas to do that?
  Thanks a lot!</p>
  <p>Edit:
  One exemple of one sheet I would like to transfer into a dataframe as read_excel would do it.</p>
