The SEC dumps data from many different file types into one large text file. See here for an example: ftp://ftp.sec.gov/edgar/data/1013934/0000950123-10-098183.txt Some of these files are binary files (in the link above, the 0000950123-10-098183-xbrl.zip is one such example)… (Budget: $30-$250 USD, Jobs: Perl)
