python熊猫到excel UnicodeDecodeError：'ascii'编解码器无法解码位置11的字节0xe2

Question

After the web scraping of an e-commerce web site I have saved all the data into a pandas dataframe. Well, when I'm trying to save my pandas dataframe to an excel file but I get the following error:

Traceback (most recent call last):

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 11: 
ordinal not in range(128)

The code I use is this:

df.to_excel('my_file.xlsx',sheet_name='Dolci', encoding='iso-8859-1')

but it doesn't work, I even have tried:

df.to_excel('my_file.xlsx',sheet_name='Dolci', encoding='utf-8')

but it still give me error. Can somebody help me on this issue?

Answer 1

It seems like you use xlsxwriter engine in ExcelWriter. Try to use openpyxl instead.

writer = pd.ExcelWriter('file_name.xlsx', engine='openpyxl')
df.to_excel(writer)
writer.save()

Answer 2

There is an essential param of to_excel method, try

df.to_excel('filename.xlsx', engine='openpyxl')

and it works for me.

Answer 3

Adding to @Vadym 's response, you may have to close your writer to get the file to be created.

    writer = pd.ExcelWriter(xlPath, engine='openpyxl')
    df.to_excel(writer)
    writer.close()

"depends on the behaviour of the used engine"
