Loading data
Loading data into the component does not require much effort as Webix provides several ways to do it. You can either load files by setting a remote/local URL or parse the contents of an uploaded file by using the related Webix API.
Excel file uploading and downloading
Excel Viewer API provides the possibility to upload the files for viewing and download them back to your local machine.
Upload an Excel file by clicking on the "Select" button
Customizing data presentation
The widget allows you to decide how Excel data will be presented. For example, you can customize column headers as well as specify whether to visualize spanned cells. Also, if your Excel file is nicely styled, all the styles will be rendered in the viewer.
