How to convert a PowerPoint PPTX to Text TXT in Node.JS

We are here today to look at how to extract all of the text out of a PowerPoint presentation using Node.JS. Straightforward enough, but how can we turn this task into a no-brainer? Well, that’s easy. We’ll use an API to do all the work for us!

We begin with installation of our client, accomplished with this reference added to our package.json file.

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

Now that we have access to our client, we can proceed to call our function as you see here:

var CloudmersiveConvertApiClient = require('cloudmersive-convert-api-client');
var defaultClient = CloudmersiveConvertApiClient.ApiClient.instance;
// Configure API key authorization: Apikey
var 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.convertDocumentPptxToTxt(inputFile, callback);

Now just input your PPTX file and the API will convert it into text. Super easy.
