In your "Manage Snips" section, there is a link on the right hand sidebar called "Excel-ready Snips". 

Once you're logged in on the Snipr/Snipurl website, pull up Excel and on a blank worksheet, and click on the DATA --> IMPORT EXTERNAL DATA --> NEW WEB QUERY, as follows:

A small window will popup, telling you to specify a URL.  Enter the Address: "http://snipr.com/site/allsnips" and click on "Go". It will load that page right within Excel, and look something like this: 

Just click on the IMPORT button, and you'll have your snips in your Excel file. You can save this file, and just DATA --> REFRESH DATA whenever you wish to see the latest activity on your snips. 

Simple! 

Microsoft Excel is tied to Internet Explorer, so you will have to login through Internet Explorer, even
if you generally use another browser (I use Firefox and Opera). I have not tested this feature on Mac,
but would love to hear experiences of users.
