Library to read and write CSV files with Clojure.
The original library was written by Miki Tebeka. This is a fork with additional features, mostly dealing with improving the API.
Assume log.csv has the following data
Date,IP 2/20/11 7:58 AM,1.0.1.0
Then you can do
; Simple use
(let [records (read-csv "log.csv")]
(println ((first records) 0)))
;=> Date
; With headers
(let [records (read-csv "log.csv" :headers? true)]
(println ((first records) "IP")))
;=> 1.0.1.0
; With conversion
(let [df (DateFormat/getInstance)
convert {"Date" #(.parse df %)}
records (read-csv "log.csv" :headers? true :convert convert)]
(println ((first records) "Date")))
;=> #<Date Sun Feb 20 07:58:00 PST 2011>
; Simple usage
(write-csv [[1 2 3] [4 5 6]] "points.csv")
; With headers
(write-csv [[1 2 3] [4 5 6] "points.csv" :headers ["x" "y" "z"])
; Write maps, first map will be used as headers information
(write-csv [{"x" 1 "y" 2 "z" 3} {"x" 4 "y" 5 "z" 6}] "points.csv")
; Use a formatter
(def format { "x" : #(str (* % 2)) })
(write-csv [{"x" 1 "y" 2 "z" 3} {"x" 4 "y" 5 "z" 6}] "points.csv"
:format format)
; Use a different delimiter
(write-csv [[1 2 3] [4 5 6]] "points.csv" :delimiter \|)
