Subject [jira] [Resolved] (SANDBOX-263) Excel strategy uses wrong separator
Date Tue, 06 Mar 2012 11:32:58 GMT

     [ https://issues.apache.org/jira/browse/SANDBOX-263?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Emmanuel Bourg resolved SANDBOX-263.
------------------------------------

    Resolution: Fixed

I added a note in the Javadoc explaining that the list separator is specific to the locale.
CSVFormat.EXCEL must be constant so it's not possible to guess the separator here.

>             Project: Commons Sandbox

> The Excel strategy is defined as follows.
> {code}
>     public static CSVStrategy EXCEL_STRATEGY   = new CSVStrategy(',', '"', COMMENTS_DISABLED,
ESCAPE_DISABLED, false, 
>                                                                  false, false, false);
> {code}
> However, when I do a "Save as" in Excel the separator used is actually {{';'}}. Thus,
parsing the CSV file as suggested in the JavaDoc of {{CSVParser}} fails.
> {code}
> String[][] data =
>    (new CSVParser(new StringReader("a;b\nc;d"), CSVStrategy.EXCEL_STRATEGY)).getAllValues();
> {code}
> Simple test to reproduce:
> {code}
> import java.io.IOException;
> import java.io.StringReader;
> import org.apache.commons.csv.CSVParser;
> import org.apache.commons.csv.CSVStrategy;
> public class CSVExcelStrategyBug {
> 	public static void main(final String[] args) {
> 		try {
> 			System.out.println("Using ;");
> 			parse("a;b\nc;d");
> 			System.out.println();
> 			System.out.println("Using ,");
> 			parse("a,b\nc,d");
> 		} catch (final IOException e) {
> 			e.printStackTrace();
> 		}
> 	}
> 	private static void parse(final String input) throws IOException {
> 		final String[][] data = (new CSVParser(new StringReader(input), CSVStrategy.EXCEL_STRATEGY)).getAllValues();
> 		for (final String[] row : data) {
> 			System.out.print("[");
> 			for (final String cell : row) {
> 				System.out.print("(" + cell + ")");
> 			}
> 			System.out.println("]");
> 		}
> 	}
> }
> {code}
> Actual output:
> {noformat}
> Using ;
> [(a;b)]
> [(c;d)]
> Using ,
> [(a)(b)]
> [(c)(d)]
> {noformat}
> Expected output:
> {noformat}
> Using ;
> [(a)(b)]
> [(c)(d)]
> Using ,
> [(a,b)]
> [(c,d)]
> {noformat}
