How to replace blank space with new line? in notepad++ regex

Question

I have a list of some data which is in this format for example

word1 word2 word3

word4 word5

word6 word7 word8 word9

but I want to split it all up so that each word is in new line so it would become like:

word1

word2

word3

word4

word5

word6

word7

word8

word9

the blank space between the words is perfect seperator which could be used in search&replace but Not sure of what would the code be in notepad++ regex search?

Thanks

Answer 1

Entering \s+ on the Find what field and \n (Change to \n\n for two new lines) on the Replace With field followed by Replace All transforms:

word1 word2 word3

word4 word5

word6 word7 word8 word9

onto:

word1
word2
word3
word4
word5
word6
word7
word8
word9
