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()

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()
