Open local or remote XLSX, XLS, ODS, CSV (comma separated), TSV (tab separated), other delimited, fixed-width files, and Google Docs. Returns an enumerator of Arrays or Hashes, depending on whether there are headers.

Like jq or grep for csv. Combine one or more CSVs while filtering on fields with regular expressions, whitelists, presence, missing, etc.

Helps you spawn new inner views and lookup the right one.
