<b><a href="https://sheetjs.com">SheetJS + AngularJS demo</a></b>

The core library can be used as-is in AngularJS applications.
The <a href="https://docs.sheetjs.com">Community Edition README</a> details some common use cases.
We also have some <a href="https://docs.sheetjs.com/docs/demos/">more public demos</a>

This demo shows:
- SheetJSExportService: a service for exporting data from a ui-grid
- SheetJSImportDirective: a directive providing a file input button for import
