File and Document Conversion API – .NET SDK Installation

In order to convert PDF to Word Doc, I will be using the .NET SDK of GroupDocs.Conversion Cloud API. It is a fast secure, feature-rich, and reliable file format conversion platform. C# .NET API can convert back and forth between over 50 types of files, including all formats like PDF, HTML, CAD, raster images, and many more. It also allows you to convert and extract format-specific information from a wide list of supported source document formats into any supported document format. Additionally, it provides a flexible set of settings to customize the conversion process. Currently, it supports Java, PHP, Ruby, Python, CSharp,and Node.js SDKs as its document conversion family members

You can download and install it to your VS Code project from the NuGet Package manager or add it using the following command in the Package console:

dotnet add package GroupDocs.Conversion-Cloud --version 22.10.0

Next, get the Client ID and Client Secret from the dashboard before you start following the steps and available code snippets. Add your Client ID and Client Secret in the code as demonstrated below:

//Get clientId & clientSecret from https://dashboard.groupdocs.cloud (free registration is required).
string clientId = "xxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx";
string clientSecret = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx";
string myStorage = "test-internal-storage";
var configuration = new Configuration(clientId, clientSecret);
configuration.ApiBaseUrl = "https://api.groupdocs.cloud";
