Changes detection algorithms used by GroupDocs.Comparison Cloud allows to detect changes in different document parts and blocks:
Text blocks - paragraphs, words and characters;
Tables;
Images;
Shapes etc.
For better visual separation of detected changes added, modified or deleted document parts are highlighted with different colors:
Added – blue
Modified – green
Style – green
Deleted – red
Changes styling coloring scheme can be customized if needed, changed text blocks can be marked with different formatting - italic, bold, underlined, strikethrough etc.
The following code snippet demonstrates the simplest case of documents comparison using couple lines of code.
API usage
There are steps that usage of GroupDocs.Comparison Cloud consists of:
Upload input documents into cloud storage
Compare documents or get document info
Download comparison result document from storage
Steps 1 and 3 are storage operations, please refer to this File API documentation for usage details.
Swagger UI lets you call this REST API directly from the browser.

Using an SDK (API client) is the quickest way for a developer to speed up the development. An SDK takes care of a lot of low-level details of making requests and handling responses and lets you focus on writing code specific to your particular project. Check out our GitHub repository for a complete list of GroupDocs.Comparison Cloud SDKs along with working examples, to get you started in no time. Please check Available SDKs article to learn how to add an SDK to your project.
