New to SharePoint 2013, the Import Spreadsheet app makes
it easier than ever to collaborate with team members and colleagues on a
spreadsheet in SharePoint.  While Excel is a great vehicle for storing
data, it doesn’t provide the collaborative advantages such as co-authoring that
SharePoint offers. 

In this article, we’ll show you how to use the Import Spreadsheet app in SharePoint
2013 to import your Excel files into
SharePoint as lists.   

To begin, go to Settings
and select Site contents:

From Site
Contents, select add
an app:

Select the Import
Spreadsheet app:

On the new page that appears, input the Name and Description of the spreadsheet in the text boxes. Click the Browse button to locate the spreadsheet
on your hard drive.

Select the Excel
file that you wish to import and click the Import button.

After you click Import,
the Excel file will automatically
open in your server. A dialog box will appear titled Import to Windows SharePoint Services list.  The dialog will have two drop-down lists: Range Type and Select Range:

In the Range
Type drop-down, select Tab Range.

In the Select
Range drop-down, leave it set to the default option.

Once you have made your
selections, click the Import button.

Your SharePoint site will automatically display a new list that contains the data
imported from the Excel file: 

To access your file later, go to Site Contents.  Your spreadsheet will be listed under Lists, Libraries, and other Apps:
