每次通过intooufile 导出数据文件成excel表格式 下载到本地后都会成为乱码
百度后 通过转码的方式发现还是不行，只能通过导成txt格式再另存的方式成excel格式，相当麻烦，于是自己写个脚本来达到目的
源码

#!/usr/bin/python
# -*- coding: utf-8 -*-
import MySQLdb
import xlsxwriter
import os
import sys
os.remove('demo3.xlsx')
#default_encoding = 'utf8'
#if sys.getdefaultencoding() != default_encoding:
#reload(sys)
#sys.setdefaultencoding(default_encoding)


conn=MySQLdb.connect(user="root",passwd="NuyBc6jdYwU9oQ",db="vip",port=3306,host="127.0.0.1",charset="utf8")
cursor =conn.cursor()


sql="**************"


n=cursor.execute(sql)
print "row count is :",n


row=cursor.fetchall()
col=len(row[1])
print "col count is:",col


workbook = xlsxwriter.Workbook('demo3.xlsx') # 创建一个 Excel 文件
worksheet = workbook.add_worksheet() # 创建一个工作表对象


colname=['?','A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z']



####写入表头（即列名）
k=1
for field_desc in cursor.description:
name=colname[k]+"%s" % 1
m=field_desc[0].decode('utf-8')###中文别名需要加utf-8
print m
worksheet.write(name,u'%s' % m)
k=k+1




###写入数据
i=2
for data in row:
rowname="A%s" % i
print "now is:",rowname
j=1
for m in data:
name=colname[j]+"%s" % i
print m

worksheet.write(name,u'%s' % m)


j=j+1
i=i+1

workbook.close()

cursor.close()
conn.close()

执行：demo3.xlsx 下载到本地打开无乱码
[root@host-192-168-6-254 soft]# ls
