That pretty much defines my career, yes.

Say someone gives you a logfile of problematic transactions - you then have to convert all the numbers to decimal points before using them in some one-off program that checks them.

Say someone gives me a MongoDB full of transactions that need to be transformed into relational data for our data warehouse...hey, I'll bet I could make a career out of this.

I truly don't mean to be trite, but what you describe is just the way of things. In your log file example, a regex would more than likely solve the problem. One loop, a readln() and a writeln(), sorted. People do it everyday. Hell, I'll probably do something similar before the day is out.
