The Data Loading Tools are a free solution provided by Esri designed to help simplify and streamline the ETL (Extract, Transform, and Load) process from a source dataset to a target dataset. The tools are packaged as a python add-in for ArcGIS Pro and help simplify migration by harnessing Microsoft Excel spreadsheets. Within the spreadsheets migration mapping from the source schema to target schema can be set up for feature classes, fields, and even coded value domains. This toolbox is most used to assist with migrating data into the robust Utility Network schema, but it can be used for all ETL tasks!
