import EasyXLS.*;
public class Tutorial39 {
public static void main(String[] args) {
try {
System.out.println("Tutorial 39");
System.out.println("----------");

ExcelDocument workbook = new ExcelDocument();
// Import CSV file
System.out.println("Reading file C:\\Samples\\Tutorial30.csv.");
FileInputStream file = new FileInputStream("C:\\Samples\\Tutorial30.csv");
if (workbook.easy_LoadCSVFile(file))
{
// Set worksheet name
workbook.easy_getSheetAt(0).setSheetName("First tab");
// Add new worksheet and add some data in cells (optional step)
workbook.easy_addWorksheet("Second tab");
ExcelTable xlsTable = ((ExcelWorksheet)workbook.easy_getSheetAt(1)).easy_getExcelTable();
xlsTable.easy_getCell("A1").setValue("Data added by Tutorial39");
for (int column=0; column<5; column++)
{
xlsTable.easy_getCell(1, column).setValue("Data " + (column + 1));
}
// Export Excel file
System.out.println("Writing file C:\\Samples\\Tutorial39 - convert CSV to Excel.xlsx.");
workbook.easy_WriteXLSXFile("C:\\Samples\\Tutorial39 - convert CSV to Excel.xlsx");
// Confirm conversion of CSV to Excelif (workbook.easy_getError().equals(""))
System.out.println("File successfully created.");
else
System.out.println("Error encountered: " + workbook.easy_getError());
}
// Dispose memory
workbook.Dispose();
}
catch (Exception ex) {
