# Angular 1
The `xlsx.core.min.js` and `xlsx.full.min.js` scripts are designed to be dropped
into web pages with script tags e.g.
```html
<script src="xlsx.full.min.js"></script>
```
Strictly speaking, there should be no need for an angular demo! You can proceed
as you would with any other browser-friendly library. To make this meaningful,
we chose to show an integration with a common angular table component.
This demo uses angular-ui-grid to display a data table. The ui-grid does not
provide any way to hook into the import button, so the demo includes a simple
directive for a HTML File Input control. It also includes a sample service for
export which adds an item to the export menu.
## Import Directive
`SheetJSImportDirective` follows the prescription from the README for File input
controls using `readAsBinaryString`, converting to a suitable representation
and updating the scope.
## Export Service
`SheetJSExportService` exposes export functions for `XLSB` and `XLSX`. Other
formats are easily supported by changing the `bookType` variable. It grabs
values from the grid, builds an array of arrays, generates a workbook and uses
FileSaver to generate a download. By setting the `filename` and `sheetname`
options in the ui-grid options, the output can be controlled.
