Possible to extract partial data in Excel?

Hello,

I have an Excel spreadsheet that contains around 1500 html links.

All the addresses start out common... i.e. http://www.frogs.com/. What I want to extract into another cell (or worksheet) is the uncommon part of the links. For example, https://efty.com/d/404/bull_frogs
or https://efty.com/d/404/tree_frogs.

Is there a way to automate this with a macro or something, or am I stuck doing each and every one manually?
