Export XLSX - Highcharts module

This plugin adds the capability to export from Highcharts to the Excel .xlsx format. This is an updated version of the original export-xlsx plugin. I removed the moment.js and jQuery requirements and switched from SheetJS to the open source ExcelJS library for exporting. ExcelJS provides many more options for custom export formatting than SheetJS.

Demo

• https://jsfiddle.net/chrisvecchio/ds6ocjy0/

Requirements

• Latest Highcharts (tested with 8.0.0), but should work with version 7.0.0+.
• Latest Highcharts exporting and export-data modules.
• ExcelJS version 3.5.0+.
• FileSaver.js version 2.0.2+.
• SSF.js version 0.10.2+. (only needed if using auto column width feature)

Notes:

• Plugin does NO verification of ExcelJS options specifications. I recommend google, stackoverflow or the official ExcelJS docs for ExcelJS questions.
• Plugin does not check for correctly specified Excel number/date formats. A description of Excel's number format codes by Microsoft can be found here . There are plenty of other resources available on Excel number formats via a google search or stackoverflow.

Installation

• Add <script> tag pointing to export-xlsx.js below the required sources listed above.

Code

The latest code is available on github: https://github.com/chris-vecchio/export-xlsx

Usage

The plugin adds the following new options to the native Highcharts exporting options under the xlsx key.

Enable/disable auto column width calculation. Default: false Auto column width calculation requires loading SSF.js before export-xlsx. See the demo for an example of how to load SSF.js.
