python模块之XlsxWriter 详解

Xlsx是python用来构造xlsx文件的模块，可以向excel2007+中写text，numbers，formulas 公式以及hyperlinks超链接。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：1，Introduction: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2， Installing:sudo pip install XlsxWriter;sudo easy_install XlsxWriter;或者源码安装：http://github.com/jmcnamara/XlsxWriter/archive/master.tar.gz3，使用：

import xlsxwriter

workbook = xlsxwriter.Workbook('hello.xlsx') # 建立文件

worksheet = workbook.add_worksheet() # 建立sheet， 可以work.add_worksheet('employee')来指定sheet名，但中文名会报UnicodeDecodeErro的错误

worksheet.write('A1', 'Hello world') # 向A1写入

workbook.close()

excel公式计算excel自定义格式：

import xlsxwriter

# 建文件及sheet.
workbook = xlsxwriter.Workbook('Expenses02.xlsx')
worksheet = workbook.add_worksheet()

# Add a bold format to use to highlight cells. 设置粗体，默认是False
bold = workbook.add_format({'bold': True})

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

# Write some data headers. 带自定义粗体blod格式写表头
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)    # 带默认格式写入
worksheet.write(row, col + 1, cost, money)  # 带自定义money格式写入
row += 1

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

workbook.close()

excel写入时间格式@@@ write方法提供了python类型到excel类型的转换， XlsxWriter支持excel工作表最大1048576行记录，16384条列记录，超出可以选择再建新sheet关于更多字符串、数字、颜色及位置等excel格式：http://xlsxwriter.readthedocs.io/format.html4， 图标这个是我比较关注的利用excel工具进行图标统计的功能相比较python的matplotlib的画图模块，excel的图标更加漂亮灵活一些Chart: Area, Bar, Column, Doughnut, Line, Pie, Scatter, Stock, Radarworkbook = xlswriter.Workbook('chart.xls')worksheet = workbook.add_sheet('First_example') # 普通工作表建立Chart对象： chart = workbook.add_chart({type, 'column'})将图插入到sheet中： worksheet.insert_chart('A7', chart)或者可以建立图表工作表chartsheetchartsheet = workbook.add_charsheet()chartsheet.set_char(chart)柱状图：workbook.add_chart({'type':'column'}) # 默认格式workbook.add_chart({'type':'column', 'substyle':'percent_stacked'}) # 按百分比展示workbook.add_chart({'type':'column', 'substyle':'stacked'})

其他类型chart也是这样：
