Sharing Scouting data with other devices without internet

[xXhunter47Xx]

How I was going to do scouting was to have team members jot down notes and whatnot during the matches, and bring it down to a single person to input into a spreadsheet (because scrolling through a spreadsheet is faster than flipping through poorly scribbled notes in a binder).

The issue is that through this method, I suspect that my Head Scout will be constantly putting in values in the spreadsheet and as the coach I don't want to interfere with his data input when I want to pull up some info to strategize.
This can be possible with google sheets and an internet connection, but we won't have an internet connection (no hotspots allowed either).

What is one way to do this? Everything I've thought of required an internet connection or some type of network switch.
