How To Import Excel in Java JTable (GUI) Swing Application Tutorial – Netbeans

To import data from excel to java JTable you need Apache POI(Apache POI – the Java API for Microsoft Documents) library added to your project libraries section. Download and extract the compressed files from https://poi.apache.org/. This application selects excel file from the computer and displays it on java JTable . You need to click import excel button, then choose excel file you want to import. When you click open button, the file is imported and displayed on the JTable. You also get a dialog box showing that the document has been imported successfully.

Code Snippet

public void importExcelToJtableJava() {

        File excelFile;
        FileInputStream excelFIS = null;
        BufferedInputStream excelBIS = null;
        XSSFWorkbook excelImportToJTable = null;

                excelImportToJTable = new XSSFWorkbook(excelBIS);
                XSSFSheet excelSheet = excelImportToJTable.getSheetAt(0);

                for (int row = 0; row < excelSheet.getLastRowNum(); row++) {

                    JLabel excelJL = new JLabel(new ImageIcon(new ImageIcon(excelImage.getStringCellValue()).getImage().getScaledInstance(60, 60, Image.SCALE_SMOOTH)));
                    model.addRow(new Object[]{excelName, excelGender, excelProgrammingLanguage, excelSubject, excelJL});
