To automatically transfer data from a Java GUI JFrame Form to an Excel spreadsheet, you can use the Apache POI library. Here are the steps:

1. Download and add the Apache POI library to your project.

2. Create a new Excel workbook and worksheet using the following code:

   XSSFWorkbook workbook = new XSSFWorkbook();
   XSSFSheet sheet = workbook.createSheet("Sheet1");

3. Get the input data from the JTextFields or other input components in your JFrame Form.

4. Write the input data to the Excel worksheet using the following code:

   XSSFRow row = sheet.createRow(rowNum);
   XSSFCell cell = row.createCell(colNum);
   cell.setCellValue(inputData);

You can loop through the input data and write it to the worksheet in a batch.

5. Save the Excel workbook using the following code:

   FileOutputStream outputStream = new FileOutputStream("path/to/excel/file.xlsx");
   workbook.write(outputStream);
   workbook.close();

Change the file path to a valid path on your system.

By following the above steps, you can automatically transfer data from your Java GUI JFrame Form to an Excel spreadsheet using the Apache POI library.
