This article demonstrates how to merge Word documents using Spire.Doc for Java.
Document class provides an insertTextFromFile() method that let us merge Word documents by inserting content from a source document into a destination document. In the result document, the inserted content will start from a new page.
import com.spire.doc.Document;
import com.spire.doc.FileFormat;
public class MergeWordDocument {
public static void main(String[] args){
//File path of the first document
String filePath1 = "merge1.docx";
//File path of the second document
String filePath2 = "merge2.docx";
//Load the first document
Document document = new Document(filePath1);
//Insert content of the second document into the first document
document.insertTextFromFile(filePath2, FileFormat.Docx_2013);
//Save the resultant document
document.saveToFile("Output.docx", FileFormat.Docx_2013);
}
}
Output:
If you want the inserted content to follow the last paragraph of the destination document instead of starting from a new page, use the below method to clone sections of the source document and then append to the last section of the destination document.
import com.spire.doc.Document;
import com.spire.doc.DocumentObject;
import com.spire.doc.FileFormat;
import com.spire.doc.Section;
public class MergeWordDocument {
public static void main(String[] args){
//File path of the first document
String filePath1 = "merge1.docx";
//File path of the second document
String filePath2 = "merge2.docx";
//Load the first document
Document document1 = new Document(filePath1);
//Load the second document
Document document2 = new Document(filePath2);
//Get the last section of the first document
Section lastSection = document1.getLastSection();
//Add the sections of the second document to the last section of the first document
for (Section section:(Iterable )document2.getSections()) {
for (DocumentObject obj:(Iterable )section.getBody().getChildObjects()
) {
lastSection.getBody().getChildObjects().add(obj.deepClone());
}
}
//Save the resultant document
document1.saveToFile("Output.docx", FileFormat.Docx_2013);
}
}
Output:
