On a Windows machine, without downloading anything, how can I create a keybinding to paste without whitespace?

My friend’s workflow requires copying and pasting of numbers many times per day, however the numbers to be copied are rendered with spaces and the locations to paste require there to be no spaces.

Also, the company will not allow employees to download anything extra (so we can’t use AutoHotKey, for example).

That said, I believe it must be possible to do this within the constraints. Maybe with Powershell?

How can we create a keybinding that will paste the clipboard’s contents without whitespaces?
