Python之openpyxl模块的使用

pip install openpyxl

此模块只支持offce 2010,即是电子表格后缀是*.xlsx

            import
             openpyxl

wb = openpyxl.load_workbook(‘example.xlsx‘)

##### 工作表常用操作print(wb.active)  # 获取电子表格Worksheet是否有数据print(wb.read_only)  # 是否是以只读方式打开print(wb.encoding)  # 获取电子表格的编码print(‘‘, wb.properties)  # 获取电子表格属性如：标题、作者、创建时间等print(wb.worksheets)  # 获取工作表名print(wb.get_sheet_names())  # 获取工作表的所有名字print(wb.sheetnames)  # 获取工作表的所有名字跟wb.get_sheet_names()一样的功能print(wb.get_sheet_by_name(‘Sheet1‘))  # 通过工作表的名字，获取Worksheet对象操作电子表格print(wb.create_sheet(‘python创建的工作表‘))  # 创建的工作表,记得用save保存，才保存到硬盘上print(wb.copy_worksheet(wb[‘Sheet1‘]))  # 复制工作表#### 工作表的常用操作
sheet1_obj = wb[‘Sheet1‘]
print(sheet1_obj.title)  # 工作表的标题print(sheet1_obj.dimensions)  # 获取表格大小，返回格式如：A1:D6print(sheet1_obj.max_row)  # 表格最大行数print(sheet1_obj.min_row)  # 表格最小行数print(sheet1_obj.max_column)  # 表格最大列数print(sheet1_obj.min_column)  # 表格最小列数print(sheet1_obj.rows)  # 按行获取单元格(Cell对象)print(sheet1_obj.columns)  # 按列获取单元格(Cell对象)print(sheet1_obj.freeze_panes)  # 冻结窗格print(sheet1_obj.values)  # 按行获取表格的内容（数据）print(sheet1_obj.iter_rows())#迭代器方式，按行获取所有单元格(Cell对象)print(sheet1_obj.iter_columns())#迭代器方式，按列获取所有单元格(Cell对象)
