Any ways to remove space at the end of each line

Hi all.
Hope all is good.

Can anyone please help me with one of my requirement that is mentioned below ?

I have a word document wherein it has lots of lines in it. (approximately 1000 - 1500 lines). At the end of each and every line, there is a space given in it and I want to remove that space which is given at the end of each line.

As of now, I am doing manually which is taking lot of time.

Can anyone please tell me, is there any option where I can delete the space at the end of each line in one shot or as quick as possible ?

Thanks in advance for your time in reading this post and providing me the solution.

Find what: _^p
Replace with: ^p

undescore is a space here

Hi Alkey & Sandey,

Thanks a lot for your time and reply.

But both the solutions as you have mentioned aren't working.

Attached is just the sample for my explaination.

In the attached word file, I need to remove the spaces at the end of each line.
In each line of my attached word file, the last words are "the, dragoman, to, valuable, shoulder, it, body, was, to & his". At end of these words there are spaces and I need to remove those spaces. I don't need even a single space at the end of every line.

Thank you.
