I can't think of any data entry method more easily understood by non-programmers than an Excel spreadsheet (or Google Sheets etc). Repetitive data in particular is a breeze since you can drag-expand and use formulas. We use GSheets at work for configs created by non-programmers, and it works great.

What is your point? You can see from my previous comment I already agree excel is user friendly for non programmers.

The user-friendliness is a unique advantage of Excel.
