Default Dynamic excel widget + App Ideas?

I work for a charity.
We are moving from paper "sign-in" sheets for intake, to android devices.
and I would like to use an "excel" spreadsheet with 4 cells.
(or something anyone can think of that works for this?)

Cell #1 "Name
Cell #2: If they have proper documentation
Cell #3 People in household
Cell #4 if they have been seen or not.

Ive seen some widgets have a list that you could scroll as a widget and I would LOVE that.
Also, I need to display this on 3 "Android TV's" in three locations.
This way, the Director and two other workers could see these numbers in near real time.
It cant be a "chat" app, cus most of this info must remain secret.

I was thinking maybe saving the document to google drive,
and put the same Gmail account on all three Google tv devices?
But being able to "preview" the text/excel file in a widet that you can "scroll" (we have LONG lists 100+ entries)
is vital.

Thanks for any help or ideas.
