Textpad
Don't put the quotes, just put \n in the search textbox and leave the replace textbox empty.
To get the paragraph symbol to show up in word, click the button with the paragraph symbol on it in the toolbar. Might have to click the little down arrow thingy at the end of the bar to show more buttons, but it's there.
edit: for word:
- control+f
- goto replace tab
- put "^p" without quotes into "find what:"
- leave "replace with" blank
- click replace
