 7 #新建excel
 8 wb2=openpyxl.Workbook()
 9 wb2.save('test.xlsx')
10 print('新建成功')
11 
12 #读取数据
13 wb1=openpyxl.load_workbook('data.xlsx')
14 wb2=openpyxl.load_workbook('test.xlsx')
15 sheets1=wb1.get_sheet_names()#获取sheet页
16 sheets2=wb2.get_sheet_names()
17 sheet1=wb1.get_sheet_by_name(sheets1[0])
18 sheet2=wb2.get_sheet_by_name(sheets2[0])
19 
20 max_row=sheet1.max_row#最大行数
21 max_column=sheet1.max_column#最大列数
22 
23 for m in range(1,max_row+1):
24     for n in range(97,97+max_column):#chr(97)='a'
25         n=chr(n)#ASCII字符
26         i='%s%d'%(n,m)#单元格编号
27         cell1=sheet1[i].value#获取data单元格数据
28         sheet2[i].value=cell1#赋值到test单元格
29 
30 wb2.save('test.xlsx')#保存数据
31 wb1.close()#关闭excel
32 wb2.close()
