Fast and Accurate Comparison Engine

Fast and Accurate Comparison Engine

GroupDocs.Comparison doesn’t simply compare texts, but is able to identify changes in literally all document elements specific to each file format supported by the application. This allows you to get complete details of all changes made to a document - content, styles and layout – all are precisely analyzed and reported when differences are found.

Advanced Word Files Handling

Advanced Options for Microsoft Word Documents

When comparing two Microsoft Word documents, GroupDocs.Comparison allows you to accept or reject found changes one by one or all at once and then merge the documents into a final file either in a DOC/DOCX or PDF format. Alternatively, you can merge the documents without applying any changes and export them to a new file with the Microsoft Word’s native “Track Changes” feature enabled for further offline review and editing.
