Electron
This library is compatible with Electron and should just work out of the box.
The demonstration uses Electron 18.2.0. The library is added via require
from
the renderer process.
The library 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
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
.
The demo project is structured for electron-forge
:
npm start
will start the app.npm run make
will build a standalone app.
The standalone app was tested on an Intel Mac (darwin-x64
).
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:
/* from app code, require('electron').remote calls back to main process */
var dialog = require('electron').remote.dialog;
/* show a file-open dialog and read the first selected file */
var o = dialog.showOpenDialog({ properties: ['openFile'] });
var workbook = XLSX.readFile(o[0]);
/* show a file-save dialog and write the workbook */
var o = dialog.showSaveDialog();
XLSX.writeFile(workbook, o);
Breaking Changes in Electron
The first version of this demo used Electron 1.7.5.
Electron 9.0.0 and later require the preference nodeIntegration: true
in order
to require('XLSX')
in the renderer process.
Electron 12.0.0 and later also require worldSafeExecuteJavascript: true
and
contextIsolation: true
.
Electron 14+ must use @electron/remote
instead of remote
.
