使用openpyxl保存文件的時候，出現最下面異常，查看openpyxl 的版本是2.5.14， 把openpyxl降級就可以解決此問題。

補充：python的openpyxl 3.0.2版無法保存數據

在使用openpyxl3.0.2版的時候老是

報錯“TypeError: got invalid input value of type , expected string or Element”

在將3.0.2版的卸載并且重新安裝了3.0.0版的openpyxl之后此報錯解除！

以上為個人經驗，希望能給大家一個參考，也希望大家多多支持好吧啦網。如有錯誤或未考慮完全的地方，望不吝賜教。
