title: Is there a way to append data to an excel file without reading its contents, in python?
body: <p>I have a huge master data dump excel file. I have to append data to it on a regular basis. The data to be appended is stored as a pandas dataframe. Is there a way to append this data to the master dump file without having to read its contents. </p>
  
  <p>The dump file is huge and takes a considerable amount of time for the program to load the file (using pandas).</p>
  
  <p>I have already tried openpyxl and XlsxWriter but it didn't work. </p>
