You can do with text processing:
1/ TSV is easier : replace the first two spaces of the NT output with
real tabs. Otherwise, replace the first 2 spaces with commas and worry
about the CSV-quoting rules for literals.
2/ Use SPARQL TSV or CSV output formats on "SELECT * { ?s ?p ?o }"

Hi Laura
It's not exactly what you want, but it can be used.
It does in fact more than what you want: it creates a table from a graph
coming from any SPARQL query.
But the output is HTML, and it's not a command line (could be implemented
as such ! ).
And from the HTML table , you can obtain CSV in several ways, for example
with LibreOffice:

In the tools page, push "Table" button:

(needs login)
And then you obtain the table (no login needed):

Would it make sense to add an "--output=csv" to RIOT? In particular I'm
looking at the case of reading a file in .nt/.ttl format and outputting
triples in CSV or TSV. This would be really really handy for piping in
Bash. Unfortunately there doesn't seem to be any easy way to convert NT to
CSV, so it would be really nice if RIOT could spit out CSV. Would this make
sense?
