如何用Python修改Excel数据

在前面的文章中介绍了如何用Python读写Excel数据，今天再介绍一下如何用Python修改Excel数据。需要用到xlutils模块。下载地址为https://pypi.python.org/pypi/xlutils。下载后执行python setup.py install命令进行安装即可。

具体使用代码如下：

 1 #-*-coding:utf-8-*-

 2 from xlutils.copy import copy    # http://pypi.python.org/pypi/xlutils

 3 from xlrd import open_workbook  # http://pypi.python.org/pypi/xlrd

 4 from xlwt import easyxf         # http://pypi.python.org/pypi/xlwt

 5 

 6 import sys

 7 reload(sys)

 8 sys.setdefaultencoding('utf-8')

 9 

10 # 0 based (subtract 1 from excel row number)

11 START_ROW = 404

12 

13 ismal_index = 2

14 #url所在列

15 url_index = 12

16 #domain所在列

17 domain_index = 11

18 #malinfo所在列

19 malinfo_index = 9

20 

21 file_path = "C:\\Users\\***\\Desktop\\20130514.xls"

22 #formatting_info=True保存之前数据的格式

23 rb = open_workbook(file_path,formatting_info=True)

24 r_sheet = rb.sheet_by_index(0) # read only copy to introspect the file

25 wb = copy(rb) # a writable copy (I can't read values out of this, only write to it)

26 w_sheet = wb.get_sheet(0) # the sheet to write to within the writable copy

27 

28 malurl = '''http://xbox.ooqqxx.com/res/ext.jar

29             http://xbox.ooqqxx.com/res/stat.jar

30             http://xbox.ooqqxx.com/pages/v.html

31             http://xbox.ooqqxx.com/pages/extv.html

32             http://xbox.ooqqxx.com/pages/r.html'''

33 domain_info = "http://xbox.ooqqxx.com"

34 malinfo = u"获取恶意URL，写入配置文件中，下载恶意可执行程序。"

35 

36 #r_sheet.nrows为总行数

37 for row_index in range(START_ROW, r_sheet.nrows):

38     #xlsvalue = r_sheet.cell(row_index, col_age_november).value

39     w_sheet.write(row_index, ismal_index, u'是')

40     w_sheet.write(row_index, url_index, malurl)

41     w_sheet.write(row_index, domain_index, domain_info)

42     w_sheet.write(row_index, malinfo_index, malinfo)

43 #wb.save(file_path + '.out' + os.path.splitext(file_path)[-1])

44 wb.save("C:\\Users\\***\\Desktop\\2013.xls")

注意：

如果在写入数据（中文）时出现以下错误：

ascii codec can't decode byte 0xe8 in position 0:ordinal not in range(128)

则需加上以下代码：

import sys

reload(sys)

sys.setdefaultencoding('utf-8')

另外，则中文字符串前记得加上u.
