I've tried to cover the most common tasks that someone who runs a blog, does text editing, works a CMS, or does freelance web development might encounter. Feel free to drop me a line if you have a suggestion for a tool.
Most of the tools have been created using javascript so you should be able to change large amounts of text very quickly as the processing is done on your computer instead of being limited by a server script.
These online tools have been tested on most modern browsers and should work as expected.
Anyways I hope these online tools save you some time and needless aggravation in your life - that's what they're supposed to do. Thanks, Scott.
