GroupDocs.Merger Cloud API provides a solution to merge and split documents of all common business formats. Supported file types include PDF, Microsoft Word documents, Excel spreadsheets, PowerPoint presentations, plain and formatted text, and a long list of supported document formats. Merger API is completely independent of your operating system, database system or development language. You can use any language and platform that supports HTTP to interact with our API. Manually writing client code can be difficult, error-prone and time-consuming, therefore, we have provided and supports SDKs in many development languages in order to make it easier to communicate with the Cloud Merger API. Using the SDK for .NET, it will hide the REST API calls and will let the developers use GroupDocs.Merger Cloud API features in a native way for your .NET application.
