Convert PDF to PowerPoint using REST API in Node.js

PowerPoint is commonly used to present information in a series of separate pages or slides for group presentations within business organizations. In certain cases, you may need to convert PDF to PowerPoint presentations programmatically. In this article, we will learn how to convert PDF to PowerPoint using a REST API in Node.js.

The following topics shall be covered in this article:

PDF to PowerPoint Conversion REST API and Node.js SDK

For converting PDF to PPTX, we will be using the Node.js SDK of GroupDocs.Conversion Cloud API. Please install it using the following command in the console:

npm install groupdocs-conversion-cloud

Please get your Client ID and Secret from the dashboard before following the mentioned steps. Once you have your ID and secret, add in the code as shown below:

global.clientId = "da0c487d-c1c0-45ae-b7bf-43eaf53c5ad5";
global.clientSecret = "479db2b01dcb93a3d4d20efb16dea971";
global.myStorage = "";
const config = new groupdocs_conversion_cloud.Configuration(clientId, clientSecret);
config.apiBaseUrl = "https://api.groupdocs.cloud";

Convert PDF to PowerPoint using REST API in Node.js

We can convert PDF files into PowerPoint presentation slides by following the simple steps given below:

Upload the Document

Firstly, we will upload the PDF file to the Cloud using the code example given below:

// Open file in IOStream from local/disc.
var resourcesFolder = 'C:\\Files\\Conversion\\sample.pdf';
// Read file
fs.readFile(resourcesFolder, (err, fileStream) => {
// Construct FileApi
var fileApi = groupdocs_conversion_cloud.FileApi.fromConfig(config);
// Create upload file request
var request = new groupdocs_conversion_cloud.UploadFileRequest("sample.pdf", fileStream, myStorage);
// Upload file
fileApi.uploadFile(request);
});
