一安裝

安裝：pip install openpyxl

備註：

如果某一天庫不好使了，解決辦法如下：

1）卸載出問題的庫：
pip uninstall pandas
pip uninstall openpyxl
2)重新安裝
python -m pip install pandas -i https://pypi.tuna.tsinghua.edu.cn/simple
python -m pip install openpyxl -i https://pypi.tuna.tsinghua.edu.cn/simple

二工作簿的新建儲存和開啟：

1建立工作簿（新建-儲存）

import openpyxl as vb
path 
 
= r'C:/Users/66907/Desktop/test2021.xlsx'
workbook = vb.Workbook(path) #新建一個工作簿
workbook.save(path) #儲存工作簿

2開啟工作簿（讀取工作簿-指定工作表）

import openpyxl as vb
path = r'C:/Users/66907/Desktop/test2021.xlsx'
workbook = vb.load_workbook(path) #讀取工作簿
worksheet = workbook['1月']

三工作表的建立刪除與複製：

1顯示工作簿中所有工作表的名稱：

import openpyxl as vb
path 
 
= r'C:/Users/66907/Desktop/test2021.xlsx'
workbook = vb.load_workbook(path)
show_worksheets = workbook.worksheets #獲取所有工作表物件
for i in show_worksheets:
    print(i.title) #遍歷出每個工作表的名稱

2刪除指定的工作表:

import openpyxl as vb
path = r'C:/Users/66907/Desktop/test2021.xlsx'
workbook = vb.load_workbook(path) #開啟工作簿
worksheet = workbook['
 
3月'] #指定工作表
workbook.remove(worksheet) #刪除指定工作表
workbook.save(path) #在原表儲存
備註：如果要另存為新檔案，指定一個新的path即可！

3新建指定名稱的工作表：

import openpyxl as vb
path = r'C:/Users/66907/Desktop/test2021.xlsx'
workbook = vb.load_workbook(path) #開啟工作簿
workbook.create_sheet('3月') #建立工作表3月
workbook.save(path) #儲存工作簿

4複製指定名稱的工作表並給表重新命名：

import openpyxl as vb
path = r'C:/Users/66907/Desktop/test2021.xlsx'
workbook = vb.load_workbook(path) #讀取工作簿
copysheet = workbook.copy_worksheet(workbook['3月']) #複製工作表
copysheet.title = '4月' #修改工作表名
workbook.save(path) #儲存工作簿

四練習：

1如何批量新建工作表

import openpyxl as vb
path = r'C:/Users/66907/Desktop/test1223.xlsx'
workbook = vb.Workbook(path)
for i in range(1,32):
    workbook.create_sheet('12月' + str(i) + '日')
workbook.save(path)

2如何批量修改工作表的名字：

import openpyxl as vb
path = r'C:/Users/66907/Desktop/test1223.xlsx'
workbook = vb.load_workbook(path)
show_sheets = workbook.worksheets
for i in show_sheets:
    i.title = '北京' + '_' + i.title
workbook.save(path)

3保留含有上海兩個字的表，其餘表全部刪除：

import openpyxl as vb
path = r'C:/Users/66907/Desktop/test1223.xlsx'
workbook = vb.load_workbook(path)
show_sheets = workbook.worksheets
for i in show_sheets:
    if i.title.split('_')[0] != '上海':
        worksheet = workbook[i.title]
        workbook.remove(worksheet)
workbook.save(path)

4複製30張表然後把模板刪除：

import openpyxl as vb
path = r'C:/Users/66907/Desktop/test1223.xlsx'
workbook = vb.load_workbook(path)
for i in range(1,31):
    copysheet = workbook.copy_worksheet(workbook['模板']) #複製模板這張表
    copysheet.title = '12月' + str(i) + '日'
workbook.remove(workbook['模板']) #刪除模板表
workbook.save(path)
