sharepoint 2013 import/export list template

When you add a list to a SharePoint site, you're using a list template. SharePoint provides several list templates such as contact list, calendar, task list and more. You use these templates to create new lists for your pages and site.
Saving list templates let you reuse customized lists. A template saves fields, formulas, and formatting, and optionally, data as well. You can save a template of a custom list built from scratch, or one made from existing templates. Templates can be downloaded for archiving or uploaded to another site collection.
Simple just go to Site Content -> Click on add an app -> on left top you can get search option then you can search by your list template name -> once you find click on that Template and create a list.

Limits for data in a list template

The default limit when storing data in along with a list template is 10 MB. If you have site owner or admin permissions, you can set the limit to a maximum of 500MB. While you can set this amount, the actual usable amount is limited by the amount of memory and disk space on your server.
Saving a library as a template with a document set  is not supported. When a new library is created with a template containing a document set, you might encounter errors.
