Hi Glen, I am using OpenCSV for my development purposes. I am also facing the same issue as to parse through Blank Lines. I’ve latest version but still reader object doesn’t check for Blank Lines. Basically first, I am reading all lines by readAll and iterating through that list to get my String Array but since it doesnt have API, I’ve to check runtime. It will be great if it is inbuilt functionality.

@Himanshu Can you try with opencsv 2.0.1? I think there were some fixes about this at some stage. Feel free to raise an issue (with sample data) if it’s still not working the way you think.

Hi Glen,
I used opencsv and found that it is not handling the blank lines because the csv is having extra rows with just commas the separator for next value. Hence CsvToBean is creating a bean with blank strings, So does CSVReader does not check for only commas i.e. in nextLine.

Hi Glen, I like opencsv, great tool. Can opencsv append? I may have missed something, but every time I use the writer, it scraps the complete document, so I have to do some coding gymnastics to keep the stuff that’s already there.

hi, great csv library, iv used the CsvToBean class to map colums to beans, only problem is i need to be able to customise the csv seperator but :

ColumnPositionMappingStrategy strat = new ColumnPositionMappingStrategy();
strat.setType(YourOrderBean.class);
String[] columns = new String[] {“name”, “orderNumber”, “id”};
strat.setColumnMapping(columns);
CsvToBean csv = new CsvToBean();
List list = csv.parse(strat, yourReader)

this forces the use of the default ‘,’ seperator.
if anybody knows of way to use a custum seperator i would be very greatfull

As Li asked earlier, any thoughts on BeanToCSV class. I have a requirement like write Bean to CSV directly rather than preparing String buffer from a Bean.

Thanks in advance.
