Openpyxl can't read xlsx file, but if i save the file, it opens

Question

So, I tried to open an excel file with openpyxl with this line

wb_bs = openpyxl.load_workbook(filename=filepath)

And got this error:

C:\Users\T-Gamer\AppData\Local\Programs\Python\Python38-32\lib\site-packages\openpyxl\styles\stylesheet.py:214: UserWarning: Workbook contains no default style, apply openpyxl's default

The thing is:

• If I create the .xlsx file, it opens
• If I download the file from this specific source(the one I need) and try to open it straight away, it generates the error.
• If I run the code after I open and save the .xlsx file(no changes), it works.

I suppose it has something to do with excel version conflict, but I've tried everything and nothing seems to work.

openpyxl==3.0.5 python==3.8.5

This seems to be an Openpyxl bug regarding some Excel files, reported here: https://foss.heptapod.net/openpyxl/openpyxl/-/issues/1071

Unfortunately it looks like there's no fix, just the workaround you've found:

In the just released version of Excel (Version 1803 (Build 9126.2259 Click-to-Run)), Microsoft has modified the way hyperlinks are stored in Excel files. As a workaround, you could try opening and re-saving the file in Google Sheets or LibreOffice. I am experiencing similar issues with data validation.

The reason may be the security prevention of MS-Windows: Whenever you download an MS-Office file from an outer source (internet), MS-Windows inserts a flag in that file which marks the file to be opened in protected view only. That protection stays still until you enable editing and save the file with the security flag set off.

The warning text that appears when you open a newly downloaded MS-Office file:

PROTECTED VIEW
Be careful - files from the Internet can contain viruses.
Unless you need to edit, it's safer to stay in Protected View.

I was facing the same problem. I meant to do something with pandas.read_excel() , and it return Empty Dataframe if I don't open and save the xlsx manually. So here's my code, at least it works now…

import openpyxl
import pandas as pd

file_path = r’t.xlsx’
def foo():
    return pd.read_excel(file_path)

data = foo()
if data.emty:
    writer = openpyxl.load_workbook(file_path)
    writer.save(file_path) # simply re-save it
    data = foo()
