Thank you very much for this. I hadn't considered 32bit at all and it seems like it had never been supported (many of your changes are to early code sections).

[davidanthoff]

Could you maybe tag a new release also? I'm trying to fix some CI runs downstream, and once things are tagged we should be good :)

[TimG1964]

I will. It'll be tomorrow now though, I'm afraid.

Maybe a cheeky request @davidanthoff, but can you reciprocate by responding to this PR on ExcelFiles?

At present, FileIO docs say it will read/write Excel files but this isn't true and hasn't been for quite a few years. I don't think this kind of misrepresentation is helpful.

Thanks. 🙂
