I have a pipe delimited string of NAME|VALUE pairs looking something like this..


What I want to do is to replace every second instance of | with a new line so that I have something like this..


My issue isn't the new-line, as I know I can use \r\n for that, but rather the regex part that only replaces every second instance of |.


Find: ([^\|]*\|[^\|]*)\|
Replace to: \1\n

    That doesn't work. – DavidPostill Aug 19 '15 at 8:56

    I tried this, but this just adds a new line without actually splitting the string at the |'s – Pieter van Niekerk Aug 19 '15 at 8:56
  • I've corrected and tried, it works for me now. Sorry for the previous version. – Máté Juhász Aug 19 '15 at 9:00
  • @nixda: it was working for me also before your correction, | isn't a special character in that situation, it doesn't need to be escaped – Máté Juhász Aug 19 '15 at 9:04
  • In my Notepad version (6.6.9) they need to be escaped. Don't know what to tell. Its just not working without – nixda Aug 19 '15 at 9:06

I want to replace every second instance of | with a new line

  • Menu "Search" > "Replace" (or Ctrl + H)

  • Set "Find what" to (.*?\|.*?)[\|]

  • Set "Replace with" to \1\r\n

  • Enable "Regular expression"

  • Click "Replace All"

    enter image description here






  • The above assumes you are editing a text file with Windows EOLs, \r\n.

  • If you are using files with different EOLs you can convert them to Windows EOLs using Menu "Edit" > "EOL Conversion".

  • If you aren't working with Windows EOL, and you don't wish to convert them, use the following instead:

    • Use \n instead of \r\n for Unix/OS X EOLs

    • Use \r instead of \r\n for Mac OS (up to version 9) EOLs

Further reading

  • The regex provided is rather questionable: the first .*?, as a non-greedy match, will never match anything because there is nothing to its left to anchor it. It effectively becomes a no-op. – Bob Jan 3 '18 at 3:45
