python 解析Excel

公司背景：好吧LZ太懒了.略...

原由起因：公司老板发话要导出公司数据库中符合条件的数据，源数据有400万，符合条件的大概有70万左右吧.

最终目的：符合条件的数据并生成Excel

翠花，上代码：

由于LZ python的底子并不是很好只会写一些简单的脚本，全当是记录学习里程了。此次采用的是openpyxl，因为查到它支持Excel2010

还有一些从网上找的记录下来　各种方法...

python读取excel文件代码：

#!/usr/bin/env python

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

# 读取excel数据

# 小罗的需求，取第二行以下的数据，然后取每行前13列的数据

import xlrd

data = xlrd.open_workbook('test.xls') # 打开xls文件

table = data.sheets()[0] # 打开第一张表

nrows = table.nrows # 获取表的行数

for i in range(nrows): # 循环逐行打印

if i == 0: # 跳过第一行

continue

print table.row_values(i)[:13] # 取前十三列

使用xlrd读取文件，使用xlwt生成Excel文件(可以控制Excel中单元格的格式)。但是用xlrd读取excel是不能对其进行操作的；而 xlwt生成excel文件是不能在已有的excel文件基础上进行修改的，如需要修改文件就要使用xluntils模块。pyExcelerator模 块与xlwt类似，也可以用来生成excel文件。
