用Openpyxl做两个Excel文件的比对

最近老是要做比对Report的工作，有个想法写个Python小程序来比对两个文件。

以前只用过xlrd库，处理的是xls文件，做一些简单的数据处理

这次在写小工具的同时也学习一下新的东西

由于报表是Office 2007类型（也就是Xlsx类型的）

上网查了下，决定采用openpyxl

Python处理Excel的四个工具

到官网上按着流程装了一发

A python library: Openpyxl

由于要拖BitBucket的源码，我还先装了SourceTree（别怕麻烦

据说SourceTree还有Git的功能，下次体验一下。

Openpyxl装好以后，直接在Python里面

from openpyxl import *

就可以直接使用了

Openxyxl Tutorial

Openxyxl还提供了一个很棒的教程（不过有点太简单了

而且这个库各种文档都不是特别详细…有什么都要跑去看它的源码是怎么做的...

最终代码如下

from openpyxl import *

def compareExcel(ename1, ename2):

    print "------------------------------------"
    print "Comparing",ename1,ename2
    # A bool to verify if 2 xlsx is the same.
    fileSame = True

    # Load workbook, and get sheetname
    wb1 = load_workbook(filename = ename1)
    wb2 = load_workbook(filename = ename2)
    sn1 = wb1.get_sheet_names()
    sn2 = wb2.get_sheet_names()

    if (sn1 != sn2):
        print "Two file has different sheets."
        print ename1,"has sheet names:", sn1
        print ename2,"has sheet names:", sn2
    else:
        sn = sn1
        for wsn in sn:
            # Get worksheet
            ws1 = wb1.get_sheet_by_name(name = wsn)
            ws2 = wb2.get_sheet_by_name(name = wsn)
            c = ws1.get_highest_column()
            r = ws1.get_highest_row()
            # This can be replace by ws1.get_dimension
            if ((ws2.get_highest_column()!= c) or (ws2.get_highest_row() != r)):
                print "DIFFERDENT at SHEET-",wsn,": Rows or columns not the same!"
                fileSame = False
            else:
