These classes makes it easier to create workbooks from scratch. The Workbook class is used to gather spreadsheets, while the Sheet class contain the actual data.
The primary use case here is to format data, coming from various source and processed by JavaScript, into CSV/ODT/XLSX files.
Instances of Workbook can be created without any parameter. Instances of Sheet are created by providing their initial content and name as an argument. Adding Sheet instance to a Workbook is done by calling Workbook.addSheet().
var data = [
[1, 2, 3],
[4, 5, 6]];
var wb = new xlsxhelper.Workbook();
var sheet = new xlsxhelper.Sheet('SheetName', data);
wb.addSheet(sheet);
wb.createFile('odt', 'basefilename', downloader);Classes to create PPTX presentations with images. This helper main goal is to semi-transparently allow the download of images for integration into the output.
Dynamic generation of a presentation slide depending on user-specific actions.

var pptx = new pptxhelper.Presentation();
var slide = pptx.addSlide();
slide.addText(0, 0, "Hello");
slide.addImage(5, 2, 1, 1, '/img/carret.jpg');
pptx.download('sample');Include the 'dist/xlsxhelper.js' file somewhere before you use it.
