Fastest route for multiple destinations

One day I had to visit many destinations. Like a list of addresses and postal codes. I had no idea where to go, or even, in what order to visit them. Should I sort them by postal code? Or should I draw a map and try to figure out the fastest sequence?

I looked for a innovative, online website to figure this our for me. A route planner that could help me finding the fastest route, optimizing the waypoints. I had a list of locations in Microsoft Excel and I justed wanted to copy and paste them in a route optimizer. I wanted to share the route via e-mail, put it on social media like Facebook and Twitter. Even more, I want to download it for my navigation device (Tomtom, Garmin and Navigon).

Then I found RouteXL (http://www.routexl.com) which was exactly what I needed. It is a great online web app that's free to use. They have apps for Android and Chrome, and their website is a breeze to use on iPad and iPhone. I am so happy with this free online route optimizer!
