这个python openpyxl“ValueError”是什么意思？

Question

我无法确定为什么会出现此错误。有谁知道这个错误的原因是什么？

Traceback (most recent call last):

我使用此代码收到此错误：

excel_mb_path = "C:\\Users\\Book1.xlsx"

wb1 = load_workbook(excel_mb_path , read_only=True, keep_vba=False, data_only=True, keep_links=False)

有趣的是，对于其他 excel 文件，我没有收到此错误...因此我很好奇一个完全“新的 excel”（我正在尝试阅读的一张表和一张表）有什么问题...和其他 Excel，我只是将值复制到其中，而不是代码工作的整个工作表。

Answer 1

我将给出一个有根据的猜测：

• 最后一行 (

  ValueError: Value must be one of {0, 1, 2, [...]

  ) 告诉我们 Excel 文件中的 some 值包含不受支持的值。
• 向上追溯，我们看到这个：

  [...] openpyxl\styles\alignment.py", line 59, in __init__

  ，这让我相信这与文本对齐有关。 考虑到这一点，最后一行变得更有趣：
Value must be one of {0, 1, [...] 179, 180}
• ：可能的值范围从 0 到 180。那么这可能与文本旋转有关吗？
是否可以正常工作的 Excel 文件没有任何旋转文本，而失败的文件

却有

？如果是的话，您可以尝试取消旋转并重试吗？

Answer 2

或者 使用 read_only = True，

wb = load_workbook(filename,read_only = True)
