• python模块之XlsxWriter


    官网Tutorial:http://xlsxwriter.readthedocs.io/tutorial

    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.gz

    3,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

    # Some data we want to write to the worksheet.
    expenses = (
        ['Rent', 1000],
        ['Gas',   100],
        ['Food',  300],
        ['Gym',    50],
    )
    
    # Start from the first cell. Rows and columns are zero indexed. 按标号写入是从0开始的,按绝对位置'A1'写入是从1开始的
    row = 0
    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)
        row += 1
    
    # Write a total using a formula.
    worksheet.write(row, 0, 'Total')
    worksheet.write(row, 1, '=SUM(B1:B4)')    # 调用excel的公式表达式
    
    workbook.close()
    

    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

    from datetime import datetime
     import xlsxwriter
    
     # Create a workbook and add a worksheet.
     workbook = xlsxwriter.Workbook('Expenses03.xlsx')
     worksheet = workbook.add_worksheet()
    
     # Add a bold format to use to highlight cells.
     bold = workbook.add_format({'bold': 1})
    
     # Add a number format for cells with money.
     money_format = workbook.add_format({'num_format': '$#,##0'})
    
     # Add an Excel date format.
     date_format = workbook.add_format({'num_format': 'mmmm d yyyy'})
    
     # Adjust the column width.
     worksheet.set_column(1, 1, 15)
    
     # Write some data headers.
     worksheet.write('A1', 'Item', bold)
     worksheet.write('B1', 'Date', bold)
     worksheet.write('C1', 'Cost', bold)
    
     # Some data we want to write to the worksheet.
     expenses = (
         ['Rent', '2013-01-13', 1000],
         ['Gas',  '2013-01-14',  100],
         ['Food', '2013-01-16',  300],
         ['Gym',  '2013-01-20',   50],
     )
    
     # Start from the first cell below the headers.
     row = 1
     col = 0
    
     for item, date_str, cost in (expenses):
         # Convert the date string into a datetime object.
         date = datetime.strptime(date_str, "%Y-%m-%d")
    
         worksheet.write_string  (row, col,     item              )
         worksheet.write_datetime(row, col + 1, date, date_format )
         worksheet.write_number  (row, col + 2, cost, money_format)
         row += 1
    
     # Write a total using a formula.
     worksheet.write(row, 0, 'Total', bold)
     worksheet.write(row, 2, '=SUM(C2:C5)', money_format)
    
     workbook.close()
    

     @@@ 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

    worksheet.write(0, 0, 'Hello')          # write_string()
    worksheet.write(1, 0, 'World')          # write_string()
    worksheet.write(2, 0, 2)                # write_number()
    worksheet.write(3, 0, 3.00001)          # write_number()
    worksheet.write(4, 0, '=SIN(PI()/4)')   # write_formula()
    worksheet.write(5, 0, '')               # write_blank()
    worksheet.write(6, 0, None)             # write_blank()

    4, 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, Radar

    workbook = 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chartsheet 

    chartsheet = workbook.add_charsheet()

    chartsheet.set_char(chart)

    柱状图:

    import xlsxwriter
    
    workbook = xlsxwriter.Workbook('chart.xlsx')
    worksheet = workbook.add_worksheet()
    
    # Create a new Chart object.
    chart = workbook.add_chart({'type': 'column'})
    
    # Write some data to add to plot on the chart.
    data = [
        [1, 2, 3, 4, 5],
        [2, 4, 6, 8, 10],
        [3, 6, 9, 12, 15],
    ]
    
    worksheet.write_column('A1', data[0])  # 按列插入
    worksheet.write_column('B1', data[1])
    worksheet.write_column('C1', data[2])
    
    # Configure the chart. In simplest case we add one or more data series.
    chart.add_series({'values': '=Sheet1!$A$1:$A$5'})
    chart.add_series({'values': '=Sheet1!$B$1:$B$5'})
    chart.add_series({'values': '=Sheet1!$C$1:$C$5'})
    
    # Insert the chart into the worksheet.
    worksheet.insert_chart('A7', chart)
    
    workbook.close()
    

    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:
