Both NeoCSV and NeoJSON can operate in two ways, (1) without the definition of any schema's or (2) with the definition of schema's and mappings. The quick and dirty explore style is most certainly possible.

'my-data.csv' asFileReference readStreamDo: [ :in | (NeoCSVReader on: in) upToEnd ].

  => an array of arrays

'my-data.json' asFileReference readStreamDo: [ :in | (NeoJSONReader on: in) next ].

  => objects structured using dictionaries and arrays
