On a wiki page, I would like to create a link to an Excel document stored in the Documents folder on SharePoint, that opens the Excel file in Excel Online.

When I create the link using Insert -> Link -> From SharePoint, I can select the Excel document. However, when clicking on the link, my browser (IE10) downloads the Excel file to my local hard drive.
I would like the file to open in my browser in Excel Online.
Is there a way to do this?

We use SharePoint 2013.
