pptx2json v0.0.8

pptx2json

Operating Powerpoint file (Microsoft Office 2007 and later) as Office Open XML without external tools, just pure Javascript.
Providing two main functions:

• Parse from a PowerPoint file to Json
• Parse from a Json to PowerPoint

The images, movies, audio files and so on in a PowerPoint are treated as binary.
This is strongly inspired from pptx-compose.

$ npm install pptx2json

Usage

Parse a PowerPoint file to Json

const PPTX2Json = require('pptx2json');
const pptx2json = new PPTX2Json();

const json = await pptx2json.toJson('path/to/pptx');

If you want to get a buffer below:

const PPTX2Json = require('pptx2json');
const pptx2json = new PPTX2Json();

const json = await pptx2json.toJson('path/to/pptx');
:
// return buffer to pptx 
const pptx = await pptx2json.toPPTX(json);

Otherwise want to write a file below:

const PPTX2Json = require('pptx2json');
const pptx2json = new PPTX2Json();

const json = await pptx2json.toJson('path/to/pptx');
:
// write pptx to the path 
await pptx2json.toPPTX(json, {'file': 'path/to/output.pptx'});

Get max id, rid in slides.

const PPTX2Json = require('pptx2json');
const pptx2json = new PPTX2Json();

const json = await pptx2json.toJson(testPPTX);
const ids = pptx2json.getMaxSlideIds(json);
// {'id': 5, 'rid': 3}

Get slideLayoutType Hash.

const PPTX2Json = require('pptx2json');
const pptx2json = new PPTX2Json();

const json = await pptx2json.toJson(testPPTX);
const table = pptx2json.getSlideLayoutTypeHash(json);
// {
//    'title': 'ppt/slideLayouts/slideLayout1.xml',
//    'blank': 'ppt/slideLayouts/slideLayout7.xml'
