Pretty cool! I'll try it out in more detail.
I also liked a similar product, aimed more at ETL/ML/AI segment, that was recently posted on HN: https://hal9.ai
Question: I added a 'HTTP Request' which returns JSON data, but connecting it to the 'Sort' block shows a warning/error: 'Data input is not valid. Accepted types are: DATASET'. So how do you convert JSON to a dataset?
