利用python实现对excel文件进行加密

import win32com.client

def encrypt_excel(file_path, password):
    excel = win32com.client.Dispatch("Excel.Application")
    excel.Visible = False
    excel.DisplayAlerts = False

    workbook = excel.Workbooks.Open(file_path)
    workbook.SaveAs(file_path, None, password)
    workbook.Close()
    excel.Quit()

# 加密Excel文件
encrypt_excel('C:/Users/Desktop/新建 XLSX 工作表.xlsx', '123456')

import msoffcrypto
import io

# 打开Excel文件
Excel_file='C:/Users/Desktop/新建 XLSX 工作表.xlsx'
with open(Excel_file, 'rb') as file:
    encrypted = io.BytesIO()
    office_file = msoffcrypto.OfficeFile(file)
    office_file.load_key(password='your_password')
    office_file.encrypt(encrypted)
    encrypted.seek(0)
    with open(Excel_file, 'wb') as encrypted_file:
        encrypted_file.write(encrypted.read())

from openpyxl import load_workbook

# 加载Excel文件
Excel_file='C:/Users/Desktop/新建 XLSX 工作表.xlsx'
workbook = load_workbook(Excel_file)

# 设置加密密码
password = "your_password"

# 加密Excel文件
workbook.security.workbookPassword = password
workbook.security.lockStructure = True

# 保存加密后的文件
workbook.save(Excel_file)
