GroupDocs.Comparison for Cloud plugin will allow your visitors to compare documents directly on your Umbraco website. They will be able to do this in a browser window on any web-enabled device, without having to install any office software.
All differences between the two documents will be highlighted and your visitors will be able to quickly navigate through them with a click of a button. If something was added to the second version of the document, this text will be marked with an underline. If a part of the text was removed, it will be marked with a strikeout. Anyone familiar with Word Change Tracking feature will understand those highlights intuitively, since Word marks text changes exactly the same way.
Whether you need to compare two Word documents, Excel Spreadsheets, PDF documents or even PowerPoint presentations, GroupDocs.Comparison will do this for you in a matter of seconds. The full list of supported file formats is below:
