Online Tools to sort text or replace
To sort some text or to replace some text parts, this can be easily done with text editors like Notepad++ or Edit Plus or other software. As alternative, you can do this quickly online, using websites gskinner.com or textfixer.com. For Regular Expression tests I found Flash RegExr really good as tool.
