Is It Possible To Embed Excel Worksheet Into A WebApp?

I'm trying to embed an excel spreadsheet into my webapp, where users can add formulas and do their calculations from my app, just like they would on their local Excel spreadsheet. I've never done this before clearly, and I have little knowledge with backend dev.

What would be the best way to go about this?
Is there any material anyone can share to guide me in accomplishing this obstacle?

Any suggestions would be highly appreciated. Please share your tekniks.
