Bad news first: Yahoo Pipes is shutting down by the end of September 2015. For further details, read the post about it in the Yahoo Pipes Blog.

There is a way to export individual pipes (in the hope that some day another software will come alone, that replaces the Yahoo Pipes functionality and is able to import those files). How to export a pipe is described in the above mentioned post.

This scripts adds a direct export link in the context menu for each pipe in the pipes overview list.
