自动化办公:python操作Excel
1.安装
-- upgrade pip
python -m pip install
--- install pypi
pip install pypi
执行python setup.py install进行安装xlrd
Python操作Excel,主要用到xlrd和xlwt这两个库,即xlrd是读Excel,xlwt是写Excel的库
pip install xlrd
pip install xlwt
pip install xlutils
pip install xlsxwriter
2.操作一个简单的Excel文档
操作注释及代码:
# 引入依赖模块 import xlsxwriter # 数据准备 datas = ( ['Rent', 1000], ['Gas', 100 ], ['Food', 300 ], ['Gym', 50 ], ) # 创建一个Excel文档 workbook = xlsxwriter.Workbook('ex01.xlsx') # 添加一个工作表 worksheet = workbook.add_worksheet() # 设置行和列的偏移 row, col = 0, 0 # 开始添加数据 for item, cost in datas: # 指定行、列的单元格,添加数据 worksheet.write(row, col, item) worksheet.write(row, col+1, cost) # 行增加 row += 1 # 添加一个计算总数的函数 worksheet.write(row, 0, 'Total') worksheet.write(row, 1, '=SUM(B1:B4)') # 关闭文档 workbook.close()
操作完成后,数据存储结果如下:

3. 操作简单Excel文档并添加数据格式
操作代码如下:附带数据格式的定义
# 导入依赖的模块 import xlsxwriter # 数据准备 datas = ( ['Rent', 1000], ['Gas', 100 ], ['Food', 300 ], ['Gym', 50 ], ) # 创建表格 workbook = xlsxwriter.Workbook('ex02.xlsx') worksheet = workbook.add_worksheet('data') # 添加全局格式 bold = workbook.add_format({'bold': True}) # 添加money格式 money = workbook.add_format({'num_format': '$#,##0'}) # 添加表格头,附带格式 worksheet.write('A1', 'Item', bold) worksheet.write('B1', 'Cost', bold) # 数据表格偏移 row, col = 1, 0 # 添加数据 for item, cost in datas: # 按照行列单元格添加数据 worksheet.write(row, col, item) worksheet.write(row, col+1, cost) row += 1 # 添加一列求和计数 worksheet.write(row, 0, 'Total', bold) worksheet.write(row, 1, '=SUM(B2:B5)', money) # 存储退出 workbook.close()
操作效果如图所示:

4.Excel中添加不同类型的数据
操作代码如下:将不同的数据按照指定的格式添加到文件中
# 引入依赖的模块 from datetime import datetime import xlsxwriter # 数据准备 datas = ( ['Rent', '2018-05-13', 1000], ['Gas', '2018-05-14', 100], ['Food', '2018-05-16', 300], ['Gym', '2018-05-20', 50], ) # 创建表格 workbook = xlsxwriter.Workbook('ex03.xlsx') worksheet = workbook.add_worksheet('data') # 添加格式 bold_f = workbook.add_format({'bold': True}) money_f = workbook.add_format({'num_format': '$#,##0'}) # 添加日期格式new date_f = workbook.add_format({'num_format': 'mmmm d yyyy'}) # 添加对齐方式和表格宽度new worksheet.set_column(1, 1, 15) # 添加表头数据 worksheet.write('A1', 'Item', bold_f) worksheet.write('B1', 'Date', bold_f) worksheet.write('C1', 'Cost', bold_f) # 定义偏移值 row, col = 1, 0 # 添加数据 for item, date, cost in datas: date = datetime.strptime(date, '%Y-%m-%d') worksheet.write(row, col, item) worksheet.write_datetime(row, col+1, date, date_f) worksheet.write(row, col+2, cost, money_f) row += 1 # 添加计数 worksheet.write(row, 0, 'Total', bold_f) worksheet.write(row, 2, '=SUM(C2:C5)', money_f) # 存储并关闭 workbook.close()
代码执行结果如下:

注意:xlsxwriter中提供了向excel中写入数据的多种方式,如下:
- write_string()
- write_number()
- write_blank()
- write_formula()
- write_datetime()
- write_boolean()
- write_url()
5.Excel中添加数据图表
操作代码如下:将对应的数据展示图表添加到文件中
# 引入依赖模块 import xlsxwriter # 操作数据 data = [20, 45, 26, 18, 45] # 创建表格 workbook = xlsxwriter.Workbook("ex04.xlsx") worksheet = workbook.add_worksheet("data") # 添加数据:一次添加多个数据 worksheet.write_column('A1', data) # 创建图表 chart = workbook.add_chart({'type': 'line'}) # 图表添加数据 chart.add_series({ 'values': '=data!$A1:$A6', 'name': '图表线名称', 'marker': { 'type': 'circle', 'size': 8, 'border': {'color': 'black'}, 'fill': {'color': 'red'} }, 'data_labels': {'value': True}, 'trendline': { 'type': 'polynomial', 'order': 2, 'name': '示例趋势线', 'forward': 0.5, 'backward': 0.5, 'display_equation': True, 'line': {'color': 'red', 'width': 1, 'dash_type': 'long_dash'} } }) worksheet.insert_chart('C1', chart) workbook.close()
代码执行结果如下图所示:
