The ease of use to get started quickly without needing any training or support is great! It's also very intuitive for anyone who has used other tools in this space like Excel/Power Query etc.
There are some limitations around how you can do things within easyDataTransform that might be more powerful if you're using it as part of your ETL process (eg - running multiple transformations at once). We have been able to easily automate our processes across several different environments which was not possible before we implemented EDFT into all these systems.
