如何将excel文件转换为base64，然后在python中将base64转换回excel？

Question

如何在python中将excel文件转换为base64，然后再将base64转换回excel？ 我打算将 Base64 数据存储在数据库中并按需检索并转换回 excel？有什么帮助吗？

Answer 1

import base64

def open_target_file(target_path):
    with open(target_path,"rb") as excel_file:
        return excel_file.read()

def encode_file(excel_file):
    return base64.b64encode(excel_file)

def decode_file():
    return base64.b64decode(excel_file)

your_excel_path = ""
destiny_path = ""

excel_file = open_target_file()
encoded_excel = encode_file(excel_file)
decoded_excel = decode_file(encoded_excel)

with open(destiny_path, "wb") as decoded_file:
    decoded_file.write(decoded_excel)

这样的事情应该可以工作。
