python excel自动化办公（Python办公自动化10个方法）

自动化办公，我相信很多人都有强烈的需求，都希望从繁琐重复的劳动中挣脱出来，把精力用在有意义的事情上。

现代办公室里几乎任何一项工作都会用到Excel、Word。在之前文章中我已分享过Python自动化操作word的文章《Python办公自动化｜只需三秒，一键生成数据分析报告》。

今天我教大家如何利用Python自动化操作Excel，包括：介绍操作Excel的工具包、安装方法及操作Excel具体方法。对于每天有大量重复性工作的同学来说，这款工具绝对是福利。

openpyxl是一个Python库，用于读取/写入Excel xlsx / xlsm / xltx / xltm文件。它的诞生是因为缺少可从Python本地读取/写入Office Open XML格式的库。官方文档：

http://yumos.gitee.io/openpyxl3.0

使用pip安装openpyxl。建议在不带系统软件包的Python virtualenv中执行此操作：

pip install openpyxl

支持流行的lxml库（如果已安装）。这在创建大文件时特别有用。

from openpyxl import Workbook wb = Workbook() ws_00 = wb.active #默认不取名称 ws_00['A1']= 'Python学习与数据挖掘' ws_01 = wb.create_sheet("new_sheet", 0) # 取一个new_sheet的名称 ws_01['A1']= 23 wb.save('/Users/***/Desktop/document.xlsx')

from openpyxl import Workbook from openpyxl.utils import get_column_letter wb = Workbook() dest_filename = '/Users/****/Desktop/empty_book.xlsx' ws1 = wb.active ws1.title = "range names" for row in range(1, 40): ws1.append(range(600)) ws2 = wb.create_sheet(title="Pi") ws2['F5'] = 3.14 ws3 = wb.create_sheet(title="Data") for row in range(10, 20): for col in range(27, 54): _ = ws3.cell(column=col, row=row, value="{0}".format(get_column_letter(col))) wb.save(filename = dest_filename)

from openpyxl import Workbook from openpyxl.drawing.image import Image wb = Workbook() ws = wb.active ws['A1'] = 'You should see three logos below' img = Image('/Users/***/work/logo.png') ws.add_image(img, 'A1') wb.save('/Users/***/document01.xlsx')

删除列F:H

ws.delete_cols(6, 3)

df = DataFrame(ws.values)

from openpyxl import Workbook from openpyxl.chart import ( AreaChart, Reference, Series, ) wb = Workbook() ws = wb.active rows = [ ['Number', 'Batch 1', 'Batch 2'], [2, 40, 30], [3, 40, 25], [4, 50, 30], [5, 30, 10], [6, 25, 5], [7, 50, 10], ] for row in rows: ws.append(row) chart = AreaChart() chart.title = "Area Chart" chart.style = 13 chart.x_axis.title = 'Test' chart.y_axis.title = 'Percentage' cats = Reference(ws, min_col=1, min_row=1, max_row=7) data = Reference(ws, min_col=2, min_row=1, max_col=3, max_row=7) chart.add_data(data, titles_from_data=True) chart.set_categories(cats) ws.add_chart(chart, "A10") wb.save("area.xlsx")

from openpyxl import Workbook from openpyxl.chart import ( RadarChart, Reference, ) wb = Workbook() ws = wb.active rows = [ ['Month', "Bulbs", "Seeds", "Flowers", "Trees & shrubs"], ['Jan', 0, 2500, 500, 0,], ['Feb', 0, 5500, 750, 1500], ['Mar', 0, 9000, 1500, 2500], ['Apr', 0, 6500, 2000, 4000], ['May', 0, 3500, 5500, 3500], ['Jun', 0, 0, 7500, 1500], ['Jul', 0, 0, 8500, 800], ['Aug', 1500, 0, 7000, 550], ['Sep', 5000, 0, 3500, 2500], ['Oct', 8500, 0, 2500, 6000], ['Nov', 3500, 0, 500, 5500], ['Dec', 500, 0, 100, 3000 ], ] for row in rows: ws.append(row) chart = RadarChart() chart.type = "filled" labels = Reference(ws, min_col=1, min_row=2, max_row=13) data = Reference(ws, min_col=2, max_col=5, min_row=1, max_row=13) chart.add_data(data, titles_from_data=True) chart.set_categories(labels) chart.style = 26 chart.title = "Garden Centre Sales" chart.y_axis.delete = True ws.add_chart(chart, "A17") wb.save("radar.xlsx")

业务中需要批量处理的操作，我们可以代码化。Python利用Excel的公式功能来处理数据，可以达到事半功倍的效果。

from openpyxl import Workbook from openpyxl import load_workbook wb = load_workbook('/Users/***/work/document01.xlsx') ws1=wb.active ws1["F2"] = "=SUM(B2:E2)" # 使用公式 # Save the file wb.save('/Users/***/Desktop/document01.xlsx')

# -*- coding: utf-8 -*- from openpyxl import Workbook from openpyxl.styles import colors from openpyxl.styles import Font wb = Workbook() ws = wb.active a1 = ws['A1'] d4 = ws['D4'] ft = Font(color=colors.RED) # color="FFBB00"，颜色编码也可以设定颜色 a1.font = ft d4.font = ft # If you want to change the color of a Font, you need to reassign it:: #italic 倾斜字体 a1.font = Font(color=colors.RED, italic=True) # the change only affects A1 a1.value = "abc" # Save the file wb.save("/Users/***/Desktop/document01.xlsx")

# -*- coding: utf-8 -*- from openpyxl import Workbook from openpyxl.styles import colors from openpyxl.styles import Font wb = Workbook() ws = wb.active a1 = ws['A1'] d4 = ws['D4'] a1.value = "abc" from openpyxl.styles import Font from copy import copy ft1 = Font(name=u'宋体', size=14) ft2 = copy(ft1) #复制字体对象 ft2.name = "Tahoma"

# -*- coding: utf-8 -*- from openpyxl import Workbook from openpyxl.styles import Font from openpyxl.styles import NamedStyle, Font, Border, Side,PatternFill wb = Workbook() ws = wb.active highlight = NamedStyle(name="highlight") highlight.font = Font(bold=True, size=20,color= "ff0100") highlight.fill = PatternFill("solid", fgColor="DDDDDD")#背景填充 bd = Side(style='thick', color="000000") highlight.border = Border(left=bd, top=bd, right=bd, bottom=bd) print dir(ws["A1"]) ws["A1"].style =highlight # Save the file wb.save("/Users/***/Desktop/document01.xlsx")
