import java.text.SimpleDateFormat;
import java.util.Date;

public class MailMerge {
    public static void main(String[] args) throws Exception {

        String output = "output/mailMerge.docx";

        //Create a Document instance
        Document document = new Document();

        //Add a section
        Section section = document.addSection();

        //Add 3 paragraphs to the section
        Paragraph para = section.addParagraph();
        Paragraph para2 = section.addParagraph();
        Paragraph para3 = section.addParagraph();

        //Add mail merge templates to each paragraph
        para.setText("Contact Name: ");
        para.appendField("Contact Name", FieldType.Field_Merge_Field);
        para2.setText("Phone: ");
        para2.appendField("Phone", FieldType.Field_Merge_Field);
        para3.setText("Date: ");
        para3.appendField("Date", FieldType.Field_Merge_Field);

        //Set the value for the mail merge template by the field name
        Date currentTime = new Date();
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
        String dateString = formatter.format(currentTime);
        String[] filedNames = new String[]{"Contact Name", "Phone", "Date"};
        String[] filedValues = new String[]{"John Smith", "+1 (69) 123456", dateString};

        //Merge the specified value into template
        document.getMailMerge().execute(filedNames, filedValues);

        //save the document to file
        document.saveToFile(output, FileFormat.Docx);
