xlsx and xlsm files return badzipfile: file is not a zip file

Question

I'm trying to open both an xlsx file and an xlsm file both give me the same error

badzipfile: file is not a zip file

here is what I'm typing:

import openpyxl
wb=openpyxl.load_workbook('c:\\users\\me\\documents\\filename.xlsm', keep_vba=True)
wb2=openpyxl.load_workbook('c:\\users\\me\\documents\\filename2.xlsx')

both load_workbook commands result in the same error. They both exist at that location. why am I getting this error?

Answer 1

The same problem occurred to me, and then I noticed the following:

When I created the .xlsx file from file manager, by creating new document with .xlsx format, I had the same error. But when I created the file with some spreadsheet software (libreoffice-calc) in my case, it just worked fine. I hope this may help.

Answer 2

It's because you created empty .xlsx with no metadata which is an empty file with no cells formatting. use exel or equivalent spreadsheet software to save empty file in that directory, which will create an xlsx file with cell formating, after saving try to load file using openpyxl

Answer 3

I'm late to the party, but I received the same error, but for different reasons.

On my mac, when I cut and pasted the .xlsx file into the directory I desired, it didn't actually place the file itself, it placed a symbolic link. That, for some reason, would raise the same error. I remedied this by opening the file, and using "save as".

Answer 4

My hunch is that either you openpyxl version is not the latest (2.3.1) or that there is a problem with your source file. To upgrade to the newest version to openpyxl, use:

pip install openpyxl --upgrade

Is the source file encrypted at all?

Answer 5

This also happened to me when I pointed openpyxl to an alias of the file instead of the original file.

Answer 6

I did something really stupid and got the same error. Basically, today was my first time trying this and I got it to work with the 'Automate' example and then tried my Excel. Didn't work! Took me a while to realize the error was due to having workbook password protected. The error doesn't match that at all, but when I removed the protection from the workbook, it worked! What can I say but 'duh' and 'yeah!'?
