GroovyCSV

GroovyCSV is a library for Groovy which aims to make csv data easier to work with. The library was inspired by @goeh's ExcelBuilder that lets you iterate over rows in the excel file using eachLine and access values using the column names.

Important

Package structure was changed from com.xlson.csvparser to com.xlson.groovycsv between release 0.1 and 0.2.

Features

Value-access by header name
Iteration using the ordinary collection methods (findAll, collect and so on)
Full support for OpenCSV's configurability

Example

The parse method returns an iterator over the rows in the csv. This means we can use any of the default groovy ways to iterate, in this example we see the for each loop in use.

@Grab('com.xlson.groovycsv:groovycsv:0.2')
import com.xlson.groovycsv.CsvParser

def csv = '''Name,Lastname
Mark,Andersson
Pete,Hansen'''

def data = new CsvParser().parse(csv)
for(line in data) {
    println "$line.Name $line.Lastname"
}

Output:

Mark Andersson
Pete Hansen

Building

GroovyCSV uses Gradle for building. Gradle handles the dependencies for you so all you need to do is install gradle and then build the code.

Build instruction

Download and install Gradle 0.9-rc-2
Fetch the latest code: git clone git://github.com/xlson/groovycsv.git
(Optional) Run the tests using gradle test
Go to the project directory and run: gradle jar

You will find the built jar in ./build/libs. If you need any dependencies you can download them using gradle downloadDeps, they end up in the lib folder.
