获取文件对象

import openpyxl
file = '1.xlsx'  #文件路径
wb = openpyxl.load_workbook(file, data_only=True) # 打开文件

获取 工作簿中所有工作表名的列表

wb.get_sheet_names()

获取工作表

#按名字：
wb.get_sheet_by_name('要操作的工作表名')

#索引：
details_sheet = wb.worksheets[0] #按wb.get_sheet_names() 列表顺序读取

读写

#读：
head = details_sheet.cell(row=1, column= 1).value  #row 第几行  column 第几列

#写：
details_sheet.cell(row=1, column= 1).value='插入的数据'


#按大写字母操作
head = details_sheet.cell(A, A).value # A = 1

保存

# 保存的文件名
template_file="2.xlsx"
wb.save(template_file)
