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.
Installation
$ npm install pptx2jsonUsage
Parse a PowerPoint file to Json
const PPTX2Json = require('pptx2json');
const pptx2json = new PPTX2Json();
const json = await pptx2json.toJson('path/to/pptx');Rebuild a PowerPoint from Json
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'
// }
