无法使用openpyxl加载工作簿：在处理上述异常期间，发生了另一个异常

Question

我想用openpyxl 2.5.0编辑xlsx文件。

这是我的代码，它适用于空文件：

from openpyxl import load_workbook

wb = load_workbook(filename="Untitled.xlsx")
ws = wb.active
ws["B5"] = "test"
wb.save("Export.xlsx")

但是，如果我尝试加载此文件 ，我会收到以下模糊错误。

Traceback (most recent call last):
  File "C:\Matteo\PyCharm\CMakeR\venv\lib\site-packages\openpyxl\descriptors\base.py", line 57, in _convert
    value = expected_type(value)
ValueError: invalid literal for int() with base 10: 'l'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "C:\Matteo\PyCharm\CMakeR\XLSXEditor.py", line 3, in <module>
    wb = load_workbook(filename="Modulo CMR.xlsx")

    raise TypeError('expected ' + str(expected_type))
TypeError: expected <class 'int'>

我真的不知道可能导致它的原因。 但是从搜索互联网，我收集到它可能与样式/格式转换问题有关。

感谢Charlie Clark，我注意到 - 如果我将openpyxl降级到2.4.9 - 我可以解决这个问题。 所以它似乎是与2.5.0相关的某种错误。

Answer 1

今天看起来只有两种解决方案：

1. 从Excel工作簿中删除图形。
2. 降级到openpyxl版本<2.5.0。
