Python 使用XlsxWriter操作Excel

2023-11-23 14:50 由 微软技术分享 发表于 #后端开发

在数据处理和报告生成的领域中，Excel 文件一直是广泛使用的标准格式。为了让 Python 开发者能够轻松创建和修改 Excel 文件，XlsxWriter 库应运而生。XlsxWriter 是一个功能强大的 Python 模块，专门用于生成 Microsoft Excel 2007及以上版本（.xlsx 格式）的电子表格文件。本文将对XlsxWriter进行概述，探讨其主要特点、用法和一些实际应用，并实现绘制各类图例（条形图，柱状图，饼状图）等。

主要特点

  1. .xlsx 格式支持： XlsxWriter 专注于创建 Microsoft Excel 2007 及以上版本的文件，这是一种基于 XML 的格式，允许存储大量数据、样式和图表。
  2. 格式和样式： XlsxWriter 允许开发者以编程方式设置单元格的格式和样式，包括字体、颜色、对齐方式等。这使得生成的 Excel 文件能够呈现出精美的外观。
  3. 图表和图形： XlsxWriter 支持创建各种类型的图表，如折线图、柱状图、饼图等，使用户能够直观地呈现数据。同时，它还支持插入图片、形状和注释等图形元素。
  4. 公式和函数： XlsxWriter 允许在单元格中使用 Excel 公式和函数，这对于进行复杂的计算和数据分析非常有用。
  5. 大数据量处理： XlsxWriter 被设计为高性能的库，能够处理大规模的数据集，同时保持生成的 Excel 文件的高质量。
  6. 图表和条件格式： 除了基本的单元格样式，XlsxWriter 支持添加条件格式，以及在工作表中插入图表，提供更直观的数据可视化。

安装模块

要开始使用 XlsxWriter，首先需要安装该库。可以通过以下命令使用 pip 安装：

pip install XlsxWriter

XlsxWriter 提供了一个强大而灵活的工具，使得使用 Python 生成 Excel 文件变得简单而高效。无论是用于数据分析、报告生成还是其他领域，XlsxWriter 都为开发者提供了一种简单而可靠的方法，使他们能够充分利用 Excel 的强大功能。在掌握了基本用法后，开发者可以深入研究 XlsxWriter 的高级特性，以满足更复杂的需求。

单行输出函数

函数WriteSingleArticle()调用时传入文档名称，以及传入表头和数据，写出简单的单行记录。

import xlsxwriter

# 写出数据
def WriteSingleArticle(xls_name,header,data):
    workbook = xlsxwriter.Workbook(xls_name)
    worksheet = workbook.add_worksheet()

    # 定义表格样式
    head_style = workbook.add_format({"bold": True, "align": "center", "border": 1, "fg_color": "#D7E4BC"})
    worksheet.set_column("A1:D1", 15)

    # 写出表头
    worksheet.write_row("A1", header, head_style)
    for index in range(0, len(data)):
        worksheet.write_row("A{}".format(index + 2), data[index])

    workbook.close()
    return True

if __name__ == "__main__":
    headings = ["用户名", "密码", "地址"]
    data = [["admin","123456","192.168.1.1"],["admin","123456","192.168.1.1"]]

    ref = WriteSingleArticle("lyshark.xlsx",headings,data)
    print("写出状态: {}".format(ref))

输出效果如下所示；

多行表格输出函数

函数CreateTable(address,data,section)实现了输出一个列表格式的Table，只需传入列表序列即可。

先找到表格生成坐标与大小之间的比值关系，这是第一步，如下是简单的实现固定位置生成表格。

import xlsxwriter

# 设置表格sheet名称
workbook = xlsxwriter.Workbook('lyshark.xlsx')
worksheet = workbook.add_worksheet("系统磁盘统计")

# 设置头部标题IP地址列
merge_format = workbook.add_format({'bold': True,'border': 1,'align': 'center','valign': 'vcenter','fg_color': '#EEAEEE'})
worksheet.merge_range('A9:B12', '192.168.1.1', merge_format)

# 设置表格头部提示,并将前两个表头合并为1个
header = ["IP地址","IP地址","路径","总容量","剩余容量","利用率"]
merge_format1 = workbook.add_format({'bold': True,'border': 1,'align': 'center','valign': 'vcenter','fg_color': '#AEEEEE'})
worksheet.write_row("A8:B12",header,merge_format1)        # 显示表头
worksheet.merge_range('A8:B8',"IP地址",merge_format1)      # 合并表头(合并第一个元素)

# 写出路径列表
data1 = ["/etc/system/","/proc/","/sys","/var/lyshark"]
merge_format2 = workbook.add_format({'bold': True,'border': 1,'valign': 'vcenter','fg_color': '#D7E4BC','align': 'center'})
worksheet.write_column("C9",data1,merge_format2)
worksheet.set_column("C9:C9",30)

# 写出总容量
data2 = ["1024 GB","2048 GB","111 GB","1111 GB"]
merge_format3 = workbook.add_format({'bold': True,'border': 1,'valign': 'vcenter','fg_color': '#D7E4BC','align': 'center'})
worksheet.write_column("D9",data2,merge_format3)
worksheet.set_column("D9:D9",20)

# 写出剩余容量
data3 = ["1024 GB","2048 GB","111 GB","22 GB"]
merge_format4 = workbook.add_format({'bold': True,'border': 1,'valign': 'vcenter','fg_color': '#D7E4BC','align': 'center'})
worksheet.write_column("E9",data3,merge_format4)
worksheet.set_column("E9:E9",20)

# 写出利用率
data4= ["10%","50%","20%","33%"]
merge_format5 = workbook.add_format({'bold': True,'border': 1,'valign': 'vcenter','fg_color': '#D7E4BC','align': 'center'})
worksheet.write_column("F9",data4,merge_format5)
worksheet.set_column("F9:F9",20)

workbook.close()

输出效果如下所示；

继续封装如上代码，将其封装为CreateTable(address,data,section)函数，用户传入表头地址，数据集，以及从第几行开始写数据，则自动生成表单。
