Imagine developing a new enterprise solution for your client to track changes across a series of critical MS Word document contracts, agreements, or legal paperwork that have gone through multiple revisions. Now visualize manually comparing these documents, the time it could take, and the risk of human error in missing subtle but crucial changes.

This is where automated document comparison becomes a lifesaver. Leverage the power of our Cloud SDK for .NET and easily automate Word document comparisons without worrying about platform dependencies or third-party software. In this article, we will walk you through the steps to compare Word documents, check for differences in C#, and save development time while ensuring you stay in full control.

Steps to Compare Word Documents with .NET REST API

1. Sign up and get your API credentials from the GroupDocs Cloud Dashboard.
2. Install GroupDocs.Comparison Cloud SDK for .NET using the NuGet package.
3. Set up API configuration with your client ID/Secret using the Configuration class.
4. Initialize the comparison, storage, and file API objects.
5. Upload the source and target Word files to the cloud storage.
6. Define the comparison options using the ComparisonOptions class.
7. Using the comparison API, run the comparison request and save the result.
8. Review the output file in the cloud storage to check the differences between the two Word documents, clearly highlighted for your reference.

Following these steps, you can effortlessly incorporate Word document comparison capability into your web or desktop-based C# applications. After installing the Cloud .NET SDK from NuGet, set up configurations and initialize the required APIs. Then, upload the locally stored source and target Word files to the cloud storage. Define comparison options and execute the comparison process. After the process completes, you can check the output file in the cloud storage to review the highlighted changes.
