There's nothing wrong with you, it's just a form of structuring thoughts and information just like journaling or diaries are for some people. Like Llituro said, if you learn macros and databases your skills would be invaluable for almost any company. Every company needs spreadsheets, but most of them are just basically banging rocks together and getting by with some spreadsheets some intern wrote ten years ago, mostly because no one actually understands them (there are way too many people who fill the spreadsheets by hand, then calculate the results with a calculator and fill the results in to the spreadsheet by hand).

My first office job was interning for a municipal office, and as a part of my job I did some very basic spreadsheets just to help my work (and learning it on the fly). I ended up helping people who had been working in the same office for 5-10 years whose actual work required experience with Excel. Everyone lies on their resume (as you should), but "proficient with Excel" is one of the most common lies.

E: Also, when you get the job, the next step is to learn how and what you can steal.
