How to convert a Legacy PPT Presentation to PPTX in Node.JS

Today we are going to set up a system for turning all those obsolete PowerPoint PPT files into shiny new PPTXs instead. What do you say we make this process the easiest it can possibly be? An API will do the trick. Here’s how.

Start things up by adding this dependency reference to your package.json.

"dependencies": {
"cloudmersive-convert-api-client": "^2.1.6"

This will install our API client, then allowing access to the conversion function that we need to call:

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');var defaultClient = CloudmersiveConvertApiClient.ApiClient.instance;// Configure API key authorization: Apikeyvar Apikey = defaultClient.authentications['Apikey'];Apikey.apiKey = 'YOUR API KEY';// Uncomment the following line to set a prefix for the API key, e.g. "Token" (defaults to null)//Apikey.apiKeyPrefix = 'Token';var apiInstance = new CloudmersiveConvertApiClient.ConvertDocumentApi();var inputFile = "/path/to/file"; // File | Input file to perform the operation on.var callback = function(error, data, response) {if (error) {console.error(error);} else {console.log('API called successfully. Returned data: ' + data);}};apiInstance.convertDocumentPptToPptx(inputFile, callback);

And if you now input a legacy PPT file into convertDocumentPptToPptx, you will be returned said file in its updated format. Easy as pie!

There’s an API for that. Cloudmersive is a leader in Highly Scalable Cloud APIs.
