Planmaker 2024 and openpyxl

[louyo]

Planmaker 2024, Linux, debian 12. I created a vanilla spreadsheet and saved it to .xlsx. I copied it to a system that doesn't have Planmaker. When I try to read/edit it with openpyxl library in Python, it gets an error. "TypeError: PatternFill.__init__() got an unexpected keyword argument 'extLst'".
If I run it through Libreoffice Calc, it offers to modify it for 2007-365. I can then manipulate it with Python.
Is there a way to make Planmaker save in a compatible format?

Thank you for reporting this problem. I have forwarded the details.

Please share that problematic file which you created with PlanMaker and giving error so that we can check it at our end.

If your file is private, please send it to forum[at]softmaker.com with the link of this post.

Not very complex.
from openpyxl import load_workbook
workbook = load_workbook(filename="test4py2.xlsx")
TypeError: PatternFill.__init__() got an unexpected keyword argument 'extLst'

Thank you for sharing the file. This problem is in openpyxl libraries, as it's unable to handle the keywords from the file. Ideally, it should skip the unknown keywords. So, we can't do anything here.

What keywords, may I ask?
