Does anyone have any recommendations for ETL tools that won’t break the bank? They don’t strictly need to be spatially enabled. I have just enough occasional need to benefit from one, but not enough need to justify a big expense. Thanks in advance!
Does it need to be a GUI?
Most of the ETL I do leans heavily on the Python library pandas, and I use Jupyter Notebooks to interactively build and debug the process. The geopandas extension makes it pretty easy to fold in spatial stuff as needed, and requests to ping ArcGIS REST endpoints.
I had a GUI in mind, but you make a good point about using pandas and Jupyter notebooks. The flowcharts you get as a byproduct with a GUI are handy for communicating with clients. However, Jupyter notebooks are similarly self-documenting, and the price is definitely right.
