With this native Java API, you can easily compare DOC documents and obtain the differences in the desired output format. Our Java library is fully self-contained and does not rely on any external tools or services. It eliminates the need for external dependencies, providing a comprehensive set of DOC processing functionalities within a single Java package.

On this landing page, we bring you a live demo of the DOC comparison in action, coupled with an illustrative Java example. It compares the contents of DOC documents both at the character level and at the word level. Even if only a single character has been changed, the entire word will be marked as modified. Experience firsthand how easy it is to compare two documents by uploading DOC files to the interface, choosing the desired output format, and getting the differences between DOC documents marked with 100% accuracy.

Compare DOC using Java

Sometimes it may not be clear if a DOC file has been modified, and manually comparing two versions of a document can be a daunting task. Conversely, there are times when you're sure the DOC document has changed, but visually identifying the updated sections becomes overwhelming. The DOC comparison is an increasingly sought-after procedure, particularly within automated document workflows. Let's explore typical scenarios where automated DOC comparison can be highly valuable:

Version Control and Collaboration. When multiple contributors are working on the same DOC file, programmatic document comparison helps identify changes made by different individuals
Legal and Compliance. In the legal industry, accurate comparison of legal contracts, agreements, or regulatory documents is crucial. Automated DOC file comparison ensures precise detection of any modifications, additions, or omissions, helping legal professionals maintain compliance and mitigate legal risks
Quality Assurance and Testing. Software development often involves handling extensive documentation, such as requirements, specifications, and test cases. By automating DOC comparison, Java developers can easily detect discrepancies between versions, ensuring consistency and accuracy throughout the development process
Content Management and Publishing. In content-driven industries, like publishing or journalism, maintaining consistency across different versions of articles, manuscripts, or books is essential. Comparing DOC documents programmatically allows authors and editors to quickly spot differences and ensure the integrity of their content, facilitating efficient publishing workflows

Find differences in DOC files in Java

As you can see, programmatic DOC comparison offers immense benefits in various domains, enabling streamlined workflows, enhanced collaboration, and increased productivity. With this Java API, you have the power to harness these advantages seamlessly within your Java projects. Try out our live demo by uploading two DOC documents, selecting the target format to highlight the differences, and examining the Java code example. This Java snippet demonstrates how to find differences between DOC files and save the results in the required format.

An important point: the compared DOC documents should not have revisions before calling the comparison method. You must first accept all the revisions.
