CSV

CSV reader

The CSV reader reads CSV-data from a source that may be a a string, a bytebuf, a file, a Java InputStream, or a Java Reader.

The separator and the quote char can optionally be specified. They default to a comma and a double quote.

(csv/read """
          8000,"Zurich",ZH
          5000,"Aarau",AG
          """)
            
;; => (("8000" "Zurich" "ZH") ("5000" "Aarau" "AG"))

With alternate quote and separator:

(csv/read """
          8000,'Zurich','Wipkingen, Meier''s Ring',ZH
          3000,'Bern','',BE
          5000,'Aarau',,
          """
          :separator "," 
          :quote "'")
            
;; => (("8000" "Zurich" "Wipkingen, Meier's Ring" "ZH") 
;;     ("3000" "Bern" "" "BE") 
;;     ("5000" "Aarau" nil nil))

CSV writer

Writes data in CSV format to a string or a Java Writer

(csv/write-str [[1 "AC" false] [2 "WS" true]])
  
;; => "1,AC,false\n2,WS,true"

With alternate quote, separator, and newline:

(csv/write-str [[1 "AC" false] [2 "WS;'-1'" true]]
               :quote "'"
               :separator ";"
               :newline :cr+lf)
                 
;; => "1;AC;false\r\n2;'WS;''-1''';true"

Writes data in CSV format to a file:

(csv/write (io/file "test.csv") [[1 "AC" false] [2 "WS" true]])
