Menyimpan ke satu worksheet Excel

correlations.to_excel(excel_writer= 'correlations.xls',
                      sheet_name='correlations',
                      startrow=1,
                      startcol=1)

ch4_4_v2 - Index Correlation & Saving Results to Excel.012.png

Menyimpan ke beberapa worksheet Excel

data.index = data.index.date # Keep only date component

with pd.ExcelWriter('stock_data.xlsx') as writer:

    corr.to_excel(excel_writer=writer, sheet_name='correlations')

    data.to_excel(excel_writer=writer, sheet_name='prices')

    data.pct_change().to_excel(writer, sheet_name='returns')
