I'm not sure what "Null experience" is, but process automation has varying levels of complexity and application. It can be as simple as automating a spreadsheet task for office grunts, as complex and abstract as custom building an AI to replace a human in a task, or even have concrete applications in robotics.
So I would say, figure out where and how deep you want to go, then start learning towards that end. For spreadsheet shit, just pick up a book on Javascript for Google Apps Script (or VBA for MS Office). For AI and ML, Python is good for that. For robotics, C/C++. I started in spreadsheet shit, and am now writing AIs, so you can always branch out once you master one.
I learn well from textbooks, so I would suggest that. Others learn well from videos/lectures, so you might try finding some Youtube videos or enrolling in some sort of course. And others learn best by doing, so you could just tinker and pick apart other people's code.
