title: data frame export into excel/csv
body: <p>I have created a data frame on python using melt function and other functions the final data frame i got is about 3 million rows. I need to export the data frame into excel/csv file. Which code could afford the 3M rows in the dataset.</p>
  <p>Code i have used to export is:</p>
  <pre><code>World_bank.to_csv(r'C:\Users\ITM\Documents\Gaurav Pandey\World Bank\WBSDG\World_Bank_DIET.csv')
  </code></pre>
  <p>But this is not exporting the entire dataframe.</p>
  <p>Suggest me some code which can export the large dataframe into the multiple excel sheets so that i can read entire data points.</p>
