Apimac Clean Text 4.0.2 is my choice. It is excellent
http://www.macupdate.com/info.php/id/6594Often you have to paste some text copied from one document or application into another, and you want the text to get the attributes (such as color, font, dimension and style) of the new document instead of preserving the attributes copied from the old one. Clean Text for Mac eliminates all text formatting, preparing it for pasting. Moreover, the application performs other useful functions, such as removing empty lines, removing multiple spaces, removing tab characters etc. It's also very useful for printing out text without wasting ink and paper, as often happens when you print directly from a Web browser.

Version 4.0.2: this release fixes a bug of the "Fix spaces" feature when commas, colons, dots are in numbers. Note from the product team: this application is a PowerPC-based application, we are working on making it Universal (which means made to run natively on both Intel- and PowerPC-based Mac computers), in the mean time, you can use it with some decreasing of performance with Intel-based Mac thanks to Rosetta technology (which is built into Mac OS X and dynamically translates this applications to work with Intel-based Mac).
