I am preparing for the interview process that I hope to begin in a few months, and have been thinking about different ways to make myself look more presentable/professional. I have started to grow up and make a point of keeping my logbook clean and updating it as I fly, but I did have a point where I was getting lazy about logging flights, and in the process of updating my logbook in bulk, made a few errors that don't look too pretty. I've been told it isn't a big deal because I was young and inexperienced, and I have made a concerted effort to have all my recent entries be more neat. My question is concerning the validity of bringing electronic prints of flight times to interviews.

I would rather not spend a lot of money on an expensive software program when I can make my own spreadsheet in MS Excel. If I make a nice, presentable spreadsheet with my complete flight history, and attach photocopies of all endorsements and checkrides, will that look good to an interviewer? Obviously I would bring my original book with me to the interview as well, but would it be worth it to make a nice, neat printout? I just want to maximize my professional image. When it comes time for the HR/Tech interview, should I just ask if they would like the printouts? Thanks for the input.
