Hey! I've a problem of a exceelsheets with over 10000 rows. This excel have a bad structure to do routing from a point to an other point. What I want to do is find the shortest path between these points.

It's quite easy when you have one to many. But I don't know how to do this many to many logic in the from to builder.

I have attached a workbench and a shapefile that shows the same problem I have but in as a example data.

In this example I need to make the shortest path from all in the column "from" to all area attributes. But I can't find how to build this logic without doing it manually. I've been trying with list but with no success. Can you guys help me?
