Import CSV values to an existing SharePoint List

Summary

Main idea here is import content from a csv to a existing list.

Usually for that to happen, we need to explicit enumerate each column of the list and in the csv file.

With this sample you dont need to do it anymore as long you follow the bellow rule :

CSV columns must have the same name as the list columns name.

Excelsior, hum? :P
