How to break lines at a specific character in Notepad++?

1. Click Ctrl + h or Search -> Replace on the top menu
2. Under the Search Mode group, select Regular expression
3. In the Find what text field, type ],\s*
4. In the Replace with text field, type ],\n
5. Click Replace All

Let's assume ], is the character where we wanted to break at

1. Open notePad++
2. Open Find window Ctrl+F
3. Switch to Replace Tab
4. Choose Search Mode to Extended
5. Type ], in Find What field
6. Type \nin Replace with field
7. Hit Replace All
8. Boom

Try this way. It got worked for me

1. Open Notepad++ then copy your content
2. Press ctrl + h
3. Find what is should be ,(comma) or any character that you want to replace
4. Replace with should be \n
5. Select Search Mode -> Extended (\n, \r, \t, \0)
6. Then Click on Replace All

If the text contains \r\n that need to be converted into new lines use the 'Extended' or 'Regular expression' modes and escape the backslash character in 'Find what':

Find what: \\r\\n

Replace with: \r\n
