People do this in my company even despite us having SharePoint which has decent enough support for collaborative capabilities and should in theory get rid of any need for different document versions, but that escapes many people.

This seems like a conversation from 2010. I'm not saying that to insult, but it's literally the kind of conversation I was having in a corporate environment 10+ years ago. Now, why can't you just share the link to the Excel spreadsheet and work collaboratively on the same document? If it's stored in SharePoint or OneDrive, this is trivial. There's a "Share" button in the top right corner, and you can do it from Windows Explorer as well. There's little value in emailing versions around anymore, particularly internally.
