A thin Clojure wrapper around a small part of Apache POI for reading .xlsx files.

For a more complete implementation, see the incanter-excel module from the Incanter project. Althought, currently (August 2020) Incanter uses POI 3.16.

Leiningen/Boot

[ndevreeze/excel "0.3.1"]

Clojure CLI/deps.edn

ndevreeze/excel {:mvn/version "0.3.1"}

require the namespace:

(ns your.project
  (:require [ontodev.excel :as xls]))

Use it to load a workbook and read sheets:

(let [workbook (xls/load-workbook "test.xlsx")
      sheet    (xls/read-sheet workbook "Sheet1")]
  (println "Sheet1:" (count sheet) (first sheet)))

Use the options parameter to get data back in different data formats: (xls/read-sheet {:values :values} workbook "Sheet1") (xls/read-sheet {:values :strings} workbook "Sheet1") (xls/read-sheet {:values :formatted} workbook "Sheet1")

Thanks to James Overton (ontodev) for starting this library.

• https://github.com/ontodev/excel - at version 0.2.5, using POI 3.8
• https://github.com/joshuaeckroth/excel - another fork, version 0.3.0, using POI 4.0.1

This version adds option to get data in the correct datatypes, including dates and times. Also there is an option to get the formatted data.

$ lein midje
nil
All checks (83) succeeded.

0.2.5 - base version from ontodev 0.3.0 - another fork by joshuaeckroth 0.3.1 - use POI 4.1.2, return different data formats.
