What are your everyday uses for Excel?
I've recently gotten into logging data, which started with using JEFit for my fitness tracking. I wasn't too happy with not being able to manipulate the data, so I decided to move to Excel to track my progress. Since then, I've started using it for other things, such as tracking my weight, daily caloric intake, and what changes in my diet do to my progress. I also use it to store what movies I've watched, books I've read, and albums I've listened to, along with a rating and additional comments.
I know you can do a ton of stuff with Excel, so I was just curious as to what other uses Verge readers have found for it!
