python读取txt里的json文件，存到excel,例子2

纯文本文件 numbers.txt, 里面的内容（包括方括号）如下所示：

[
   [1, 82, 65535],
   [20, 90, 13],
   [26, 809, 1024]
]
用json处理文件

# -*- coding:utf-8 -*-
import xlwt,json

with open('number.txt','r')as file_open:
    data=json.load(file_open)
    workbook=xlwt.Workbook()
    sheet=workbook.add_sheet('number')
for x,list1 in enumerate(data):
    for y,value in enumerate(list1):
        sheet.write(x,y,value)
workbook.save('numberjson.xls')

用正则表达式处理：

# -*- coding:utf-8 -*-
import xlwt,re
workbook=xlwt.Workbook(encoding='utf-8')
sheet=workbook.add_sheet('number',cell_overwrite_ok=True)
info=re.compile(r'\[(\d+), (\d+), (\d+)\]')#注意把空格也加上
def horz_rightstyle():#加了一些样式
    algnt=xlwt.Alignment()#对齐属性对象
    algnt.horz=xlwt.Alignment.HORZ_RIGHT#右对齐
    style=xlwt.XFStyle()
    style.alignment=algnt
    return style

with open('number.txt') as file_open:
    data=file_open.read()
    l=info.findall(data)
    print l
for x,list1 in enumerate(info.findall(data)):
    print x,list1
    for y,value in enumerate(list1):
        sheet.write(x,y,value,horz_rightstyle())#加右对齐样式
workbook.save('number.xls')
