# Electron
This library is compatible with Electron and should just work out of the box.
2017-09-24 23:40:09 +00:00
The demonstration uses Electron 1.7.5. The library is added via `require` from
the render process. It can also be required from the main process, as shown in
this demo to render a version string in the About dialog on OSX.
The standard HTML5 `FileReader` techniques from the browser apply to Electron.
This demo includes a drag-and-drop box as well as a file input box, mirroring
the [SheetJS Data Preview Live Demo](http://oss.sheetjs.com/js-xlsx/)
2017-09-24 23:40:09 +00:00
The core data in this demo is an editable HTML table. The readers build up the
table using `sheet_to_html` (with `editable:true` option) and the writers scrape
the table using `table_to_book`.
## Reading and Writing Files
Since electron provides an `fs` implementation, `readFile` and `writeFile` can

be used in conjunction with the standard dialog windows. For example:
```js
2017-09-24 23:40:09 +00:00
/* from app code, require('electron').remote calls back to main process */
var dialog = require('electron').remote.dialog;
2017-09-24 23:40:09 +00:00
/* show a file-open dialog and read the first selected file */
var o = dialog.showOpenDialog({ properties: ['openFile'] });
var workbook = XLSX.readFile(o[0]);
2017-09-24 23:40:09 +00:00
/* show a file-save dialog and write the workbook */
var o = dialog.showSaveDialog();
XLSX.writeFile(workbook, o);
```
