I want to add a new sheet in an excel created using .to_excel in pandas

Question

This is my code, how do I add another data frame to the same excel, say: 'df3', but on a different sheet:

df2.to_excel('Invoicing Detail Output File.xlsx', index = False)

Answer 1

Write directly to a new excel ( see ):

with pd.ExcelWriter('Invoicing Detail Output File.xlsx') as writer:
    df2.to_excel(writer, sheet_name='Sheet1')
    df3.to_excel(writer, sheet_name='Sheet2')

Or append to existing excel:

with ExcelWriter('Invoicing Detail Output File.xlsx', mode='a') as writer:
    df3.to_excel(writer, sheet_name='Sheet2')
