To save a Pandas DataFrame as an Excel file, use the DataFrame's to_excel(~) method.
WARNING
Make sure you have the openpyxl library installed - otherwise this will not work.
Saving Pandas DataFrame as Excel file
Consider the following DataFrame:
This will create an Excel spreadsheet file in the same directory as the Python script:
By default, we have an index column as well. Since we did not name the index, this column is called Unnamed.
To remove the redundant Unnamed:0 column, set index=False like so:
df.to_excel("my_excel_file.xlsx", index=False)
This would then give us the following:

import pandas as pd
def highlighter(cell_value): if cell_value in [3,6]: return "background-color: yellow"
df_new = df.style.applymap(highlighter)df_new
This produces the following in Jupyter notebook:
The beauty of the to_excel(~) method is that it preserves highlighting:
df_new.to_excel("my_excel_file.xlsx")
This produces the following Excel sheet:
