Are you planning on allowing users to enter data directly onto the spreadsheet also?
If not, you don’t really need to worry about cleaning it up too much - it’s your own design playing out.
If so, then create a single ‘entry’ sheet that is styled to 1) help users quickly fill it in and 2) distribute inputs across your other sheets as it’s filled in.
Then you can simply protect and hide all the other sheets so users only ever see the single sheet they need to deal with.
That the type of advice you’re looking for?
