所以这是我第一次尝试从Excel文件中读取，我尝试使用openpyxl模块来实现。我的目标是整理一个以嵌套列表为值的字典。但是，当我尝试运行它时，得到此警告：
用户警告：数据验证扩展不受支持，将被删除警告（msg）
我不知道我哪里做错了。任何帮助将不胜感激。谢谢

import openpyxl
try:
    wb = openpyxl.load_workbook("Grantfundme Master London.xlsx")
    except FileNotFoundError:
        print("File could not be found.")

sheet = wb["FUNDS"]

database = {}
for i in range(250):#this is the number of keys I want in my dictionary so loop through rows 
    charity = sheet.cell(row=i + 1, column=1).value

    area_of_work = []
    org = []
    funding = sheet.cell(row=i + 1, column=14).value

    for x in range(8, 13): # this loops through columns with info I need
        if sheet.cell(row=i +1, column=x).value !="":
            area_of_work.append(sheet.cell(row=i +1, column=x).value)

    for y in range(3, 6): # another column loop
        if sheet.cell(row=i +1, column=y).value !="":
            org.append(sheet.cell(row=i +1, column=y).value)

    database[charity] = [area_of_work,org, funding]

try:
    f = open("database.txt", "w")
    f.close()
except IOError:
    print("Ooops. It hasn't written to the file")

对于那些询问这里是例外的截图：（
