The native data format for Spreadsheet is JSON. When you open an excel file, it needs to be read and converted to client side Spreadsheet model. The converted client side Spreadsheet model is sent as JSON which is used to render Spreadsheet. Similarly, when you save the Spreadsheet, the client Spreadsheet model is sent to the server as JSON for processing and saved as Excel file formats. Server configuration is used for this process.
The Spreadsheet control opens an Excel document with its data, style, format, and more. To enable this feature, set allowOpen as true and assign service url to the openUrl property.
User Interface:
In user interface you can open an Excel document by clicking File > Open menu item in ribbon.
The following sample shows the Open option by using the openUrl property in the Spreadsheet control. You can also use the beforeOpen event to trigger before opening an Excel file.
// Initialize the Spreadsheet component.
var spreadsheet = new ej.spreadsheet.Spreadsheet({
allowOpen: true,
openUrl: 'https://ej2services.syncfusion.com/production/web-services/api/spreadsheet/open',
});
// Render initialized Spreadsheet.
spreadsheet.appendTo('#spreadsheet');<!DOCTYPE html><html lang="en"><head>
