Regarding your example, you can protect worksheets and have only some cells unlocked for modification [1].

You can add conditional formatting, VBA procedures, additional formulas etc. to do whatever validation you like. However, you need a software engineer (or someone who thinks like one) to properly implement that, and it’s not exactly fun.

...and in the year 2525 one still cannot avoid having their users mistakingly copy & paste formatting and thus destroy auto-extending Excel tables...

There are workarounds using VBA, but not via Typescipt - the Excel JS API knows no clipboard.
