Do any of you work with excel ONLY?

Do any of you have jobs where you use excel only? Is it remote or no? What's your academic background? What's the salary like?

I'm currently in my 2nd year as an economics major and i enjoy working with excel so i wanna see how much i can diversify my future job prospects. I'm wondering how the (literal) excel workspace is like; how did u prove to ur employer that you're good at excel (certificates from online courses or interview)? is it a highly demanded skill? Is it tiring and time consuming? If anyone can answer and provide general info about their own experiences, it'd be greatly appreaciated!
