If the command line is more of your taste, you can use
sling cli, a versatile tool to extract and load data from one platform to another. It is written in Go and uses the very same engine which powers Sling Cloud.
Running your EL tasks from the CLI has never been easier. Got a CSV or JSON file? Simple pipe the data into sling, and it will automatically detect the proper column datatypes and create a database table for you. It would look something like this:
cat my_file.csv | sling run --tgt-conn MYDB --tgt-object my_schema.my_table
