csv save data only in one cell instead of a row - excel

Question

I have the following code which writes data to the CSV file.
But instead of writing the headers each in different cell it writes all in the same cell.
When i change to "UTF-8" it works fine but writs "Gibberish" instead of correct letters when opened in Office Excel.
CSVWriter csvWrite = new CSVWriter(new OutputStreamWriter(new FileOutputStream(file),
"UTF-16"), CSVWriter.DEFAULT_SEPARATOR ,CSVWriter.NO_QUOTE_CHARACTER,
CSVWriter.DEFAULT_ESCAPE_CHARACTER, CSVWriter.DEFAULT_LINE_END);
//Add Columns headers to the excel file
String columnHeaders[] = {"אאא","בבב","גגג"};
csvWrite.writeNext(columnHeaders);
//Collect Data
ArrayList<String[]> listData = collectDataFromDBToList();
//Write/Add all line from list to the csv file
csvWrite.writeAll(listData);
csvWrite.close();
Received output
Wanted output

Answer 1

Thank phoenix but it did not helped.
I found the solution :) , it was just to use tab separator instead of the default one.
use: '\t' instead of CSVWriter.DEFAULT_SEPARATOR
CSVWriter csvWrite = new CSVWriter(new OutputStreamWriter(new FileOutputStream(file),
"UTF-16"),'\t' ,CSVWriter.NO_QUOTE_CHARACTER,
CSVWriter.DEFAULT_ESCAPE_CHARACTER, CSVWriter.DEFAULT_LINE_END);

Here is this code that i wrote for a project..the values outside for loop ( "WSDL Name" and "Tags" are the column header and list will contain values to be inserted). It will generate test.csv
import java.io.FileWriter;
import java.io.IOException;
public class genCSV
{
public static void main(String [] args)
{
generateCsvFile("c:\\test.csv");
}
private static void generateCsvFile(String sFileName)
{
try
{
FileWriter writer = new FileWriter(sFileName);
writer.append("WSDLName");
writer.append("Tags");
writer.append('\n');
for(int i=0;i<list.size();i++){
writer.append(list.getKey);
writer.append(list.getValueForKey);
writer.append('\n');
}
//generate whatever data you want
writer.flush();
writer.close();
}
catch(IOException e)
{
e.printStackTrace();
}
}
}
