After you enable the Track Changes feature in a Word document, it records all the edits in the document, such as insertions, deletions, replacements, and format changes. Track Changes is a great feature allowing you to see what changes have been made to a document. This tutorial shows how to get all revisions from a Word document by using Spire.Doc for Java.
Install Spire.Doc for Java
First of all, you're required to add the Spire.Doc.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Get All Revisions from Word
The detailed steps are as follows.
- Create a Document instance and load a sample Word document using Document.loadFromFile() method.
- Create a StringBuilder object and then 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. If yes, use Paragraph.getDeleteRevision() method to get the delete revision. Then get the revision type and author using EditRevision.getType() method and EditRevision.getAuthor() 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.
