GroupDocs.Comparison for .NET allows developers performing in-detail comparison of two different versions of documents of the same format to identify any changes within the content and text styles. The file comparison API can work with all popular document file formats including Microsoft Word (DOC, DOCX, RTF), Excel (XLS, XLSX, CSV), PowerPoint (PPT, PPTX), Outlook email (EML, MSG), OneNote, Visio, OpenDocument, PDF, HTML, AutoCAD, DjVu and images within C#, ASP.NET or any other .NET application.
The difference comparison among supported document formats is highly accurate and presented in a resultant document for further analysis. Developers can perform document comparison with different accuracy levels – low (fastest), middle (default) or high, and there are additional options available to manipulate changes styling, display summary page or not etc.
