/* ------------------------------------------------------------------------------
| Tutorial 36
|
| This tutorial shows how to read an Excel XLSX file in Java (the
| XLSX file generated by Tutorial 04 as base template), modify
| some data and save it to another XLSX file (Tutorial36 - read XLSX file.xlsx).
* --------------------------------------------------------------------------- */import java.io.FileInputStream;
import EasyXLS.*;
public class Tutorial36 {
public static void main(String[] args) {
try {
System.out.println("Tutorial 36");
System.out.println("----------");
// Create an instance of the class that reads Excel files
ExcelDocument workbook = new ExcelDocument();
// Read XLSX file
System.out.println("Reading file C:\\Samples\\Tutorial04.xlsx.");
FileInputStream file = new FileInputStream("C:\\Samples\\Tutorial04.xlsx");
if (workbook.easy_LoadXLSXFile(file))
{
// Get the table of data for the second worksheet
ExcelTable xlsSecondTable = ((ExcelWorksheet)workbook.easy_getSheetAt(1)).easy_getExcelTable();
// Write some data to the second sheet
xlsSecondTable.easy_getCell("A1").setValue("Data added by Tutorial36");
for (int column=0; column<5; column++)
{
xlsSecondTable.easy_getCell(1, column).setValue("Data " + (column + 1));
}
// Export the new XLSX file
System.out.println("Writing file C:\\Samples\\Tutorial36 - read XLSX file.xlsx.");
workbook.easy_WriteXLSXFile("C:\\Samples\\Tutorial36 - read XLSX file.xlsx");
// Confirm export of Excel fileif (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) {
ex.printStackTrace();
}
}
}
