安装模块

1、找到对应的模块 http://www.python-excel.org/

2、用pip install 安装

pip install xlrd
pip install XlsxWriter

pip list查看

XlsxWriter示例

 1 import xlsxwriter
 2 
 3 # 创建一个工作簿并添加一个工作表
 4 workbook = xlsxwriter.Workbook("demo.xlsx")
 5 worksheet = workbook.add_worksheet()
 6 
 7 # 设置列宽
 8 worksheet.set_column("A:A", 20)
 9 
10 # 设置格式
11 bold = workbook.add_format({"bold": True})
12 
13 # 设置单元格的值
14 worksheet.write("A1", "Hello")
15 
16 # 带格式的单元格
17 worksheet.write("A2", "World")
18 
19 # 写一些数字，用行列标识
20 worksheet.write(2, 0, 123)
21 worksheet.write(3, 0, 123.456, bold)
22 
23 # 插入一张图片
24 worksheet.insert_image("B5", "C:/Users/Cheng/Desktop/1.png")
25 
26 # 关闭文件流
27 workbook.close()

运行结果如下：

合并Excel数据

思路

Excel是由行和列组成的，所以这里将所有文件中的所有sheet中的数据读取出来组成一个二维数组，然后再写入新的Excel

代码

 1 import xlrd
 2 import xlsxwriter
 3 
 4 source_xls = ["D:/python/1.xlsx", "D:/python/2.xlsx"]
 5 target_xls = "D:/python/3.xlsx"
 6 
 7 # 读取数据
 8 data = []
 9 for i in source_xls:
10     wb = xlrd.open_workbook(i)
11     for sheet in wb.sheets():
12         for rownum in range(sheet.nrows):
13             data.append(sheet.row_values(rownum))
14 print(data)
15 # 写入数据
16 workbook = xlsxwriter.Workbook(target_xls)
17 worksheet = workbook.add_worksheet()
18 font = workbook.add_format({"font_size":14})
19 for i in range(len(data)):
20     for j in range(len(data[i])):
21         worksheet.write(i, j, data[i][j], font)
22 # 关闭文件流
23 workbook.close()
