For a university project, I have to create a new list with data from existing lists in SharePoint 2013. From my little experience in this field, I would use PowerShell with SharePoint's REST API to get and process the data. The problem is that I don't have administrator rights for SharePoint and thus can only use clientside technologies.
Since I am a real rookie in PowerShell and REST API, does anyone of you have an idea how to solve this problem or has some code examples that match my problem?
