How to Turn On Track Changes, Accept or Reject Changes in Word in Java

The Track Changes function in Microsoft Word makes it possible for you to make tentative edits to a document and then you can choose to accept or reject later. Spire.Doc for java supports to operate the track changes feature from code in Java applications. This article will demonstrate the feature from the following three parts.

• How to Turn On Track Changes in Word
• Get All Revisions from Word
• Accept or Reject Tracked Changes in Word

Install Spire.Doc for Java

Firstly, you need to add the Spire.Doc.jar file as a dependency in your Java application. You can download the Spire.Doc.Jar directly . If you use Maven, please use the following setting to get it.

How to Turn On Track Changes in Word

Spire.Doc for Java offers document.setTrackChanges(boolean) method to turn on or turn off the track changes function. The detailed steps are as follows.

• Create a Document instance.
• Load a sample Word document using Document.loadFromFile() method.
• Turn on the track changes function to records and changes using document.setTrackChanges(true) method.
• Making some changes on the document by adding or removing the paragraphs.
• Save the document to another file using Document.saveToFile() method.

import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.*;

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

        //Load the sample document
        Document document = new Document();
        document.loadFromFile("Sample.docx");

        //Turn on the track changes function
        document.setTrackChanges(true);

        //Insert a new paragraph
        Paragraph newPara = new Paragraph(document);
        TextRange tr= newPara.appendText("• Died: November 30, 1900 in Paris, France");
        tr.getCharacterFormat().setBold(true);
        document.getSections().get(0).getParagraphs().insert(3,newPara);

        //Remove a paragraph
        document.getSections().get(0).getParagraphs().removeAt(6);

        //Save the document to file
        document.saveToFile("Result.Docx",FileFormat.Docx);
    }
}

Get All Revisions from Word

Spire.Doc for Java offfers Paragraph.getInsertRevision() method to detect if the paragraph is newly added or not and then EditRevision.getType() method to get the type.

• Load the sample file using Document.loadFromFile() method.
• Create a StringBuilder object and using StringBuilder.append() method to log data.
• Traverse all the sections and every element under body in the section.
• Determine if the paragraph is an insertion revision or not using Paragraph.isInsertRevision() method. If yes, use Paragraph.getInsertRevision() method to get the insertion revision. Then get the revision type and author using EditRevision.getType() method and EditRevision.getAuthor() method.
• Determine if the paragraph is a delete revision or not using Paragraph.inDeleteRevision() method.
• Traverse all the elements in the paragraphs to get the text ranges' revisions.
• Write the content of StringBuilder to a txt document using FileWriter.write() method.

Accept or Reject Tracked Changes in Word

Spire.Doc for Java offers document.acceptChanges() method to accept all the revisions and document.rejectChanges() method to remove all the revisions.

• Create a Document instance and load a sample Word document using Document.loadFromFile() method.
• Accept all changes in the document using Document.acceptChanges() method.
• Reject all changes in the document using Document.rejectChanges() method.
• Save the document to another file using Document.saveToFile() method.

import com.spire.doc.*;

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

        //Load file
        Document document = new Document();
        document.loadFromFile("Result.docx");

        if (document.hasChanges()) 
            //Accept all changes
            document.acceptChanges();

            //Reject the changes
            //doc.rejectChanges();

    //Save the  document to file
        document.saveToFile("Acceptchangs.docx",FileFormat.Docx_2010);
    }
}
