Class CSVParser

java.lang.Object
com.codename1.io.CSVParser
public class CSVParser extends Object

The CSVParser allows importing data into applications quickly from a CSV source. CSV is a file format that is supported by all spreadsheets and most databases for data exchange.

The sample below lists a simple hardcoded CSV within the table:

Form hi = new Form("CSV Parsing", new BorderLayout());
CSVParser parser = new CSVParser();
try(Reader r = new com.codename1.io.CharArrayReader("1997,Ford,E350,\"Super, \"\"luxurious\"\" truck\"".toCharArray())) {
    String[][] data = parser.parse(r);
    String[] columnNames = new String[data[0].length];
    for(int iter=  0 ; iter
