Can you recommend a Java library for reading (and possibly writing) CSV files? [closed]

Answer 1

Hey, I have an open-source project for that: JFileHelpers. I think the main advantage is that it uses Java Annotations, take a look:

If you have this bean:

@FixedLengthRecord()
public class Customer {
    @FieldFixedLength(4)
    public Integer custId;

    @FieldAlign(alignMode=AlignMode.Right)
    @FieldFixedLength(20)
    public String name;

    @FieldFixedLength(3)
    public Integer rating;

    @FieldTrim(trimMode=TrimMode.Right)
    @FieldFixedLength(10)
    @FieldConverter(converter = ConverterKind.Date, 
    format = "dd-MM-yyyy")
    public Date addedDate;

    @FieldFixedLength(3)
    @FieldOptional
    public String stockSimbol;    
}

And wants to parse this file:

....|....1....|....2....|....3....|....4

2   Felipe Coury          201-01-2007
3   Anderson Polga       4212-11-2007DEF      

All you have to do is this:

FileHelperEngine engine = 
    new FileHelperEngine(Customer.class); 
List customers = 
    new ArrayList();

customers = engine.readResource(
    "/samples/customers-fixed.txt");

Also, it supports master-detail, date and format conversion, and a lot more. Let me know what you think!

Best regards!
