Document Comparison Library with a Diff View UI

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.

Advanced Support for Word Files

When comparing Word files, the library allows you to accept/reject differences and then export the resulting document to a final file in DOC/DOCX format. You can also merge and compare up to 3 versions of a Word file.

Easy to Setup

GroupDocs.Comparison works without any external dependencies and can be deployed with just a single DLL. There is no need to install any 3rd party software on the server or the client side. We also provide a C# demo, to help you explore the library quickly.

  • Portable Document Format: PDF, PDF/A
  • Microsoft Word: DOC, DOCX
  • Microsoft Excel: XLS, XLSX

Diff Generation Functionality

  • Compare contents & styles. The library can identify both content and font style changes, including bold, italic, underlines, strike-troughs, font types, etc.
  • Get comparison summary. Once documents are processed, you can save a summery list of all changes found in the result output.
  • Accept/reject changes in Word files. After applying/rejecting changes, the resulting file can be exported to a final document in DOC or DOCX format.
  • Merge & compare up to 3 Word files. The library allows you to spot which changes come from what file.
  • Support for Word's native "Track Changes" functionality. When comparing Word files, the merged document can be saved as a DOC/DOCX file, reflecting all the diffs found with the Word's native "Track Changes" feature.
  • Support for streams. Documents can be read from streams and the result output can be send to streams as well.
  • Flexible API. You can compare documents programmatically on the server side, use the library in conjunction with a built-in web UI to display diffs on the web, or built your own UI from scratch.

Web-Based Diff View UI

The library comes with a customizable web UI which displays differences between documents with a redline change tracking view. End users can view compared documents from any web-enabled device and modern web-browser. The UI provides the following options:

  • Upload documents for comparison.
  • See a list of all differences found.

  • Scroll document pages or turn them with the click of a button.
