# 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.
