Automate Excel spreadsheet comparison using the feature-rich Cloud SDK for .NET and simplify your document management workflows. This not only improves the efficiency of your applications but also guarantees that even the smallest changes in your data are identified. You can develop smart data manipulation solutions for your end-users and track differences between Excel spreadsheets containing vital financial reports, sales data, or business projections.

In this tutorial, we’ll guide you through the steps to seamlessly compare Excel spreadsheets using the C# .NET REST API to help developers integrate and expand powerful document comparison functionality within their applications across Windows, Linux, and macOS platforms.

Steps to Compare Excel Spreadsheets with C# 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. Use the Configuration class to set up the API with your client ID and secret.
4. Initialize the CompareApi and FileApi objects.
5. Upload the source and target Excel documents to the cloud storage.
6. Specify the comparison options using the ComparisonOptions class.
7. Create the comparison request using the ComparisonsRequest class and execute it using the compareApi.Comparisons() method.
8. You can now review the highlighted differences in the output file saved in the cloud storage.

These steps outline how to easily compare Excel spreadsheets for differences in your cross-platform C# .NET applications with the Cloud REST API. You can sign up to obtain your GroupDocs Cloud API credentials and install the Cloud .NET SDK from NuGet. Next, you can configure the API using your credentials. Then, initialize the comparison and file APIs and upload your local source and target spreadsheets to the cloud storage. Set up comparison options, create a comparison request, and execute it. Finally, you can check the output file in the cloud storage for differences.

Code to Compare Excel Spreadsheets in C#

We demonstrated how to compare Excel spreadsheets and check for differences using the .NET REST API in this article. You can upgrade your existing applications or create new document comparison solutions that are reliable and efficient. By incorporating this functionality into your C# applications, you can save valuable time, reduce human error, and enable users to make informed decisions faster. This is particularly valuable for industries such as finance, logistics, and research, where accuracy is critical and time is of the essence.

Additionally, the C# REST API allows comparisons for multiple file formats beyond Excel. If you are interested in Word document comparison, please check out our tutorial on how to compare Word documents in C# apps with .NET REST API.
