Excel sheet can serve as a java data source via ODBC-JDBC bridge.

Can you show a few sample rows from your spreadsheet and, using those rows, create the text file you would like as a result?

Really do need to see a sample of the workbook. Is there only one worksheet? Do you want a text file for each xml value in the spreadsheet? Are there headers in the worksheet? Is there any modification to the xml required? Are you looking to create files with .txt extensions or with .xml extensions? I do a lot of this stuff (mostly in the other direction - xml to xls, though) and just need to get a clearer picture of what you need.

public class XMLFileConverter {

	// The path for your txt files. Note the slash needs to be escaped
	public static String path = "C:\\Users\\ZW5FB\\Documents\\EE_files\\";
	
	public static void main(String[] args) throws IOException, InvalidFormatException {

		// The argument to pass in is the full path and filename for your Excel file
		String xlsFilename = args[0];
		FileInputStream fis = new FileInputStream(new File(xlsFilename));		
		Workbook wb = WorkbookFactory.create(fis);
		Sheet sheet = wb.getSheetAt(0);
		Iterator<Row> rows = sheet.rowIterator();
		while (rows.hasNext()) {
			Row row = rows.next();
			int rownum = row.getRowNum();
			if (rownum == 0) {
				continue;
			}
			String id = row.getCell(0).getStringCellValue();
			String xml = row.getCell(1).getStringCellValue().trim();
			writeFile(id, xml);
		}
	}

	public static void writeFile(String id, String xml) throws IOException {
		String txtFilename = id + ".txt";
		File file = new File(path + txtFilename);
		FileWriter fw = new FileWriter(file);

InvalidFormatException means that you compiled .class with more recent javac than you are using to run it.
