PPTX Text Parser

A minimal, pure JavaScript parser for pptx files. It will extract all the text from the slides and return it as a string or a JSON object.

Installation

npm i pptx-text-parser

Dependencies

This module requires the following dependencies:

• JSZip
• sax

Usage

To extract the text as a string, use:

const pptxTextParser = require('pptx-text-parser');

pptxTextParser('path/to/pptx/file.pptx', _mode="text")
  .then((text) => {
    console.log(text)
    return true;
  }) .catch((err) => {
    console.log(err);
    return false;
  });

To extract the text as a JSON object, use:

const pptxTextParser = require('pptx-text-parser');

pptxTextParser('path/to/pptx/file.pptx', _mode="json")
  .then((textJSON) => {
    console.log(textJSON);
  })
  .catch((err) => {
    console.log(err);
  });

Testing

Note: The contents of the sample.pptx file were generated using OpenAI's ChatGPT.

You can test the module on the sample.pptx file like so:

let sampleFilepath = "./sample.pptx";
parse(sampleFilepath, _mode="text").then((result) => {
  console.log(result);
});

Switch _mode to "json" to get the output as a JSON object.
