问题遇到的现象和发生背景
通过openpyxy 导入excel的时候，load_workbook对writer的path读取结果为None，从而无法读入相应表格。
Anaconda 4.11.0 内的Jupyter Lab 3.2.1
问题相关代码，请勿粘贴截图
import pandas as pd
import openpyxl
writer=pd.ExcelWriter('previous days swap curve.xlsx',engine='openpyxl')
book_with_formula=openpyxl.load_workbook('previous days swap curve.xlsx',data_only=False)
运行结果及报错内容

我的解答思路和尝试过的方法
这个报错提示writer的路径为空，我print out 该writer确实也是空。
我随后尝试绝对路径和相对路径，还是不行。我还尝试把openpyxl的版本升级至最新版本以及降级至3.0.1，问题依然无法解决。
且每次执行完这段代码，路径中的文件都会被损坏。
这个问题我在CSDN看过类似的情况，看完解答后依然没有头绪。请各位专家帮忙看看，谢谢。
我想要达到的结果
能正常读取含公式及多个工作表的excel表。
