I wholeheartedly agree with that. Every version of Excel is massively worse than previous one. Same with the other Office products. Incremental fixes and impovements covered with unneded features and Ribbon design.
The Ribbon interface intoduction is the most obnoxious design decision that was pushed to the keyboard and mouse users. It only helps "touch" or "pen" users and only marginally.

Is it possible to build XML parser in it?

Solving a problem you know how to solve and solved more than once is a my goto approach in learning languge or frameworks. Translation of already solved problem to the new operational model or semantic exposes a lot internal stuff and marketing double talk.
This is a lot of work and time so can not recommend it for all cases and situations.
