可以完成xlsx文件的自动化构造，包括：

合并单元格，制作excel图表等功能：

xlsxWriter支持多种excle功能；与excel完美兼容；写大文件，速度快且只占用很小的内存空间

不支持读或者改现有的excel文件

安装

pip install XlsxWriter

文档

使用

import xlsxwriter

 # Create a workbook and add a worksheet.
 workbook = xlsxwriter.Workbook('Expenses02.xlsx')
 worksheet = workbook.add_worksheet()

 # Add a bold format to use to highlight cells.
 bold = workbook.add_format({'bold': True})

 # Add a number format for cells with money.
 money = workbook.add_format({'num_format': '$#,##0'})

 # Write some data headers.
 worksheet.write('A1', 'Item', bold)
 worksheet.write('B1', 'Cost', bold)

 # Some data we want to write to the worksheet.
 expenses = (
     ['Rent', 1000],
     ['Gas',   100],
     ['Food',  300],
     ['Gym',    50],
 )

 # Start from the first cell below the headers.
 row = 1
 col = 0

 # Iterate over the data and write it out row by row.
 for item, cost in (expenses):
     worksheet.write(row, col,     item)
     worksheet.write(row, col + 1, cost, money)
     row += 1

 # Write a total using a formula.
 worksheet.write(row, 0, 'Total',       bold)
 worksheet.write(row, 1, '=SUM(B2:B5)', money)

 workbook.close()

实例演示

写一个订单的demo

import xlsxwriter
import time
import datetime

workbook = xlsxwriter.Workbook('demo.xlsx',
                               {'constant_memory': True})  # 新建excel表
worksheet = workbook.add_worksheet('订单信息')  # 新建sheet（sheet的名称为"订单信息"）

headings = ['订单编号', '付款时间', '订单人', '订单金额', '送货地址']   # 设置表头

expenses = [
    ['2020022921571600005', '2020-02-29 21:57:16', '张三', '5.00', '北京三里屯'],
    ['2020022920451600004', '2020-02-29 20:45:15', '李四', '25.80', '北京大望路'],
    ['2020022920451600035', '2020-03-29 19:45:15', '王五', '200.80', '北京清河'],

    num = float(cost)

    worksheet.write_string(row, col, item, normal_fomat)
    worksheet.write_datetime(row, col + 1, date, date_format)
    worksheet.write_string(row, col + 2, person, normal_fomat)
    worksheet.write_number(row, col + 3, num, money_format)
    worksheet.write_string(row, col + 4, addr, normal_fomat)
    row += 1

# 设置文本区格式
options = {
    'width': 256,
    'height': 50,
