[FIXED] Openpyxl load_workbook only works when I open the file manually and saves it before use

Issue

I am trying to read xlsx files using openpyxl:

workbook_skema_72 = openpyxl.load_workbook(skema_72_path)

But I get the following error when I try to load the workbook:

Traceback (most recent call last):

ValueError: Colors must be aRGB hex values

But the issue is solved when I open the workbook manually and save it. I have a lot of files so this would be difficult with all the files. Is there some sort of solution or workaround? I hope you can point me in the right direction.

Solution

I finally found a workaround maybe it will help somebody else in the future:

import os
import pyautogui
import time
    filename = ["C_72_00_a.xlsx", "C_73_00_a.xlsx", "C_74_00_a.xlsx", "C_76_00_a.xlsx"]
    path = "D:\\Python\\Intradag_opdater\\04\\2022-04-04\\LCR skema"
    
    def clean2(file_in):
        #solution 2
        open = os.path.join(path, file_in)
        os.startfile(open,'edit')
        #tilføj time sleep start og luk excel
        time.sleep(5)
        pyautogui.hotkey('ctrl', 's')
        pyautogui.hotkey('alt', 'f4')
    
    
    for x in filename:
        clean2(x)
        print(x)
