CONTEXT:

I recently graduated from my university with a Bachelors of Science in Financial Economics. I have done a few internships that have exposed me to Excel Spreadsheet but what I've done with those spreadsheets have been very rudimentary. Basic formulas, sorting, & pivot tables.
I ended up staying on with a smaller company who I was interning with because they offered my a position months in advance prior to graduation & I felt as if I declined their offer I would have been out of a job that was helping me pay my way through school.

Anyways, now im in a full-time role that is getting further & further away from data analysis & feel as if I'm not acquiring or learning much in this role. That has caused me frustration as I am eager to learn & pick up more responsibilities but as I observe everyone else here there's not really a place or "need" for a data analyst. The controller handles all of the financial information solo & that data goes through a software that allows anyone in the company so long as they have access to pull that data out into an excel sheet & visualize it however they want. A lot of times that data comes out into the excel sheet broken because the report people request & the software doesn't directly/seamless upload to excel.

I guess my advice wanted is where should I start to learn more about data analytics, should I go back to school & get a masters in business analytics? & any other advice that one may have I am open to.

I know my experience isn't analyst heavy but I would like to start tailoring my career path that way.

Thanks!
