# -*- coding: utf-8 -*-
import pandas as pd
import os.path
import os

def xls2xlsx():
    rootdir = "./xls/"
    files = os.listdir(rootdir)
    num = len(files)
    for i in range(num):
        path = rootdir + files[i]
        a = files[i].split('.')
        b = rootdir + a[0] + '.xlsx'
        x = pd.read_excel(path)
        x.to_excel(b, index=False)
xls2xlsx()

自己弄文件测试一下  中文也是可以的
