[Solved] Is there any function to write 2D Array which fetch the data into csv file?

by


You can use CSVWriter for this with writeAll() method. It doesn’t work on two dimensional array, but it works with Iterable<String[]> or List<String[]>, so you will need to do conversion first.

String[][] table = ...;
List<String[]> convertedTable = Arrays.asList(table);
CSVWriter writer = new CSVWriter(new FileWriter(csvFilename));
writer.writeAll(convertedTable);
writer.close();
