A text extraction node module, that can convert pptx and ppt file formats into pure text.
npm i pptxto.txt
var pptxtotxt = require("pptxto.txt");
When passing a URL, the URL can either be a string, or a node.js URL object. Using the URL object allows fine grained control over the URL being used.
pptxtotxt.fromUrl(url, function (error, text) {});
pptxtotxt.fromUrl(url, config, function (error, text) {});
As the result you will recieve a array, which includes all the extracted text from the pptx. You can access each slide by specifying the index of the result array.
