The local documents folder is always by default in the list of pinned folders, the ones I mentioned in the last reply. On the left side of the explorer.

In alternative, you can go to your users folder and create a shortcut in your desktop, or another location of your choice; create a shortcut for each subfolder of your choice in your desktop, or another location of your choice; or pin them in the list mentioned previously. Customize your machine to your personal preference.

I’m also speaking from personal experience, I work with Excel almost daily. Perhaps try to understand how you have your onedrive configured. Or if you don’t use it, just uninstall it and/or don’t use the autosave with cloud feature
