I have downloaded the historic accounts data from the bulk data files and parsed using the parser provided. However, the October 2024 file returns the error:
AttributeError: ‘NoneType’ object has no attribute ‘groups’
I’m not massively familiar with python so not sure where to start to investigate.
Not sure what you mean by using the “parser provided”. iXBRL is a highly specialised data format and there is not a built-in parser in python and companies house doesn’t provide a parser.
If you’re using python, I’d recommend trying Arelle (GitHub - Arelle/Arelle: Arelle open source XBRL platform) for parsing an accounts file into a workable data structure.
