We have XLS documents in SharePoint. They go through a series of changes (all stored in version history) and finally culminate in a CSV being generated. Once we create the CSV, SharePoint saves it as a separate document. In doing that, we have all the version history with our XLS and then the CSV sits alone with no version history. Is it at all possible to just have 1 document in SharePoint? This would mean the CSV being the last document and all the XLS versions saved as its version history.
