Subject [jira] [Commented] (TIKA-2826) Add a csv/tsv parser
Date Wed, 13 Feb 2019 17:59:00 GMT

Tim Allison commented on TIKA-2826:
-----------------------------------

I'm attaching the output of tika-eval comparing output on .csv files before and after adding
the parser.  When there aren't parse exceptions, the CSVParser seems to do a much better job
:D.  However, there are now parse exceptions on 1-5% of .csv files.  We may be able to improve
this somewhat, but my initial review shows that most (hand-waving...not formally measured)
of the files that caused exceptions were actually malformed csvs.

> I'm not sure I want to wade into csv/tsv detection on this ticket, but it would be great
to apply a csv parser at least for filenames ending in ".csv" or if a user "hints" that the
file is a csv via the metadata.
