python将excel数据合并的方法

xlsxwriter使用介绍：

import xlsxwriter

# 创建一个工作簿并添加一个工作表
workbook = xlsxwriter.Workbook("demo.xlsx")
worksheet = workbook.add_worksheet()

# 设置列宽
worksheet.set_column("A:A", 20)

# 设置格式
bold = workbook.add_format({"bold": True})

# 设置单元格的值
worksheet.write("A1", "Hello")

# 带格式的单元格
worksheet.write("A2", "World")

# 写一些数字，用行列标识
worksheet.write(2, 0, 123)
worksheet.write(3, 0, 123.456, bold)

# 插入一张图片
worksheet.insert_image("B5", "C:/Users/Cheng/Desktop/1.png")

# 关闭文件流
workbook.close()

合并Excel数据的方法：

import xlrd
import xlsxwriter

source_xls = ["D:/python/1.xlsx", "D:/python/2.xlsx"]
target_xls = "D:/python/3.xlsx"

# 读取数据
data = []
for i in source_xls:
    wb = xlrd.open_workbook(i)
    for sheet in wb.sheets():
        for rownum in range(sheet.nrows):
            data.append(sheet.row_values(rownum))
print(data)
# 写入数据
workbook = xlsxwriter.Workbook(target_xls)
worksheet = workbook.add_worksheet()
font = workbook.add_format({"font_size":14})
for i in range(len(data)):
    for j in range(len(data[i])):
        worksheet.write(i, j, data[i][j], font)
# 关闭文件流
workbook.close()

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。
