尝试从 openpyxl 使用模块 load_workbook 时出错

Question

I'm attempting to open an xlsx-file using load_workbook from the module openpyxl . The code I have is:

import os
from openpyxl import load_workbook

def edit_workbook():
    path = r'C:\123 ABC\Excel documents'
    filename = 'filename.xlsx'

    os.path.join(path, filename)
    workbook = load_workbook(os.path.join(path, filename))

    ## Error is on the line above.

The complete error message I get is:

Traceback (most recent call last):

  File "<ipython-input-12-22dfdfc4e5e1>", line 1, in <module>
    workbook = load_workbook(os.path.join(path, filename))

    value = _convert(self.expected_type, value)

    raise TypeError('expected ' + str(expected_type))

TypeError: expected <class 'int'>

Anyone know what this can be?

Answer 1

I received the same error. In my case, the Excel workbook has no charts, no filters, no formulas, no VBA. Only data. This workbook was generated by some third party software.

Turns out that the workbook was corrupted. I found that out when trying to save it after some very minor change. Once I resolved the corruption (by letting Excel save it to a different name as it requested), the openpyxl error disappeared.
