GroupDocs.Comparison for .NET is a lightweight library which allows you to merge and compare two versions of a PDF or Office document and display differences between them through a diff view interface.
Wide File Format Support
GroupDocs.Comparison is a one-stop solution for comparing documents of all common formats. It can be used to generate diffs for PDF files, Microsoft Word documents (DOC, DOCX), Excel spreadsheets (XLS, XSLSX), PowerPoint presentations (PPT, PPTX), TXT and HTML documents.
Intuitive Diff View UI
The library comes with a web diff UI that displays differences between compared documents through a redline change tracking view. Thanks to the flexible API, you can easily customize the UI, built your own one from scratch, or use the library without the UI.
