If it helps, here's another tutorial for the traveling salesperson problem: https://medium.com/@rihot_gusron/sol...m-e8deea89ca42 I found several other tutorials with a search string like "traveling salesman problem Excel."

I note that every Excel based tutorial that I am finding begins with building a distance matrix somewhere in the spreadsheet. I note that your sample file does not include a distance matrix anywhere, so it would appear that you should start there. How are you wanting to calculate distance between nodes? Can you build a matrix that calculates the distance between all nodes?
