pandas导出excel出现 df.to_excel() UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe5 in positio...

问题提出

import pandas as pd
df = pd.read_csv("text.csv", sep="\t")
df.to_excel("test.xlsx")

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe7 in position 7: ordinal not in range(128)

解决办法

import pandas as pd


def csv2excel(fp):
    df = pd.read_csv(fp, sep="\t")
    cols = df.columns
    ## 转换每一列的编码
    for e in cols:
        df[e] = df[e].map(lambda x: str(x).decode("utf8").encode("raw_unicode_escape").decode(
            "raw_unicode_escape"))
        # 这里的 utf8 为 python 运行环境默认编码, 即 sys.getdefaultencoding()
        print(e)
    df.to_excel(fp.replace(".csv", ".xlsx"))
    print(fp)
    
if name == "main":
    fp = "test.csv"
    csv2excel(fp)
