Data can be uploaded from a spreadsheet or other file based data source using the
Upload feature. By clicking on the Upload button in the toolbar a user can select a spreadsheet, select a sheet and map the spreadsheet columns to the database table. In this example you can download an
Excel spreadsheet and then upload into the categories table. In addition to specifying the
uploadDataTable property the mapped columns can also be fixed by specifying the mapped source column name in the
uploadDataColumn property.
