an anyone arrange this with a website,bot or notepad

I have a list of keywords around (1000+)

Keyword 1
Keyword 2
Keyword 3
Keyword 4

And want to arrange this into

Keyword1,Keyword2,Keyword3

I know there is a work around for this in notepad but if anyone could share me the exact instructions, Or could share a website or Ubot bot to do this it will be appreciated

Any help will be appreciated

Can you pm me the list and I will do it for you?

i do this all the time in notepad++

click on the end of a line after the last letter
hold shift key and hit right arrow until cursor is on the next line before first character
hit ctrl+c to copy
hit ctrl+f to open find
select replace
enter a comma in the replace string box
click replace all
the keywords should now be on one line separated by commas
