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

Question

在电子商务网站的网络抓取之后，我将所有数据保存到了pandas数据框中。 好吧，当我尝试将我的熊猫数据框保存到一个excel文件中时，出现以下错误：

Traceback (most recent call last):

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

我使用的代码是这样的：

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

但是它不起作用，我什至尝试了：

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

但它仍然给我错误。 有人可以帮我解决这个问题吗？

Answer 1

似乎您在ExcelWriter中使用xlsxwriter引擎。 尝试改用openpyxl。

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

Answer 2

有一个to_excel方法的基本参数，请尝试

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

它对我有用。

Answer 3

除了@Vadym的响应之外，您可能必须关闭编写器才能获取要创建的文件。

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