無法使用openpyxl加載工作簿：在處理上述異常期間，發生了另一個異常

Question

我想用openpyxl 2.5.0編輯xlsx文件。

這是我的代碼，它適用於空文件：

from openpyxl import load_workbook

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

但是，如果我嘗試加載此文件 ，我會收到以下模糊錯誤。

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")

    value = _convert(self.expected_type, value)
  File "C:\Matteo\PyCharm\CMakeR\venv\lib\site-packages\openpyxl\descriptors\base.py", line 59, in _convert
    raise TypeError('expected ' + str(expected_type))
TypeError: expected <class 'int'>

我真的不知道可能導致它的原因。 但是從搜索互聯網，我收集到它可能與樣式/格式轉換問題有關。

感謝Charlie Clark，我注意到 - 如果我將openpyxl降級到2.4.9 - 我可以解決這個問題。 所以它似乎是與2.5.0相關的某種錯誤。

Answer 1

今天看起來只有兩種解決方案：

1. 從Excel工作簿中刪除圖形。
2. 降級到openpyxl版本<2.5.0。
