Replace new lines with a comma delimiter with Notepad++?

Question

Open the find and replace dialog (press CTRL+H).

Then select Regular expression in the 'Search Mode' section at the bottom.

In the Find what field enter this: [\r\n]+

In the Replace with: , 

There is a space after the comma.

This will also replace lines like

Apples

Apricots
Pear

Avocados
Bananas

Where there are empty lines.

If your lines have trailing blank spaces you should remove those first. The simplest way to achieve this is

EDIT -> Blank Operations -> Trim Trailing Space

OR

TextFX -> TextFX Edit -> Trim trailing spaces

Be sure to set the Search Mode to "Regular expression".

fapDaddy's answer using a macro pointed me in the right direction.

Here's precisely what worked for me.

1. Place the cursor after the first data item.

2. Click 'Macro > Start Recording' in the menu.

3. Type this sequence: Comma, Space, Delete, End.

4. Click 'Macro > Stop recording' in the menu.

5. Click 'Macro > Run a Macro Multiple Times...' in the menu.

6. Click 'Run until the end of file' and click 'Run'.

7. Remove any trailing characters.

8. Done!

Here's what worked for me with a similar list of strings in Notepad++ without any macros or anything else:

1. Click Edit -> Blank Operations -> EOL to space [All the items should now be in a single line separated by a 'space']

2. Select any 'space' and do a Replace All (by ',')

For Notepad++ 5.9

1. Press Ctrl+H
2. Select Search mode Extended(\n, \r, \t, \o, \x...)
3. Enter Find what: \r\n
4. Enter Replace with: ,
5. Replace_All should get the required result.

A regex match with \s+ worked for me:

Place your cursor after Apples, under Macro Tab, select Start Recording. Type the comma(,) character, space( ) character, and press End key, under Macro tab, select Stop Recording.
