How to format JSON in notepad++

I want to format JSON String in notepad++. Kindly guide me how to do so. I looked into this solution Notepad ++ JSON Format. It tells me to download the a tool from This web site. But I don't know which link to click out of 4 mentioned in that web site. Also, I just randomly downloaded one of the zip file and then unzipped it and it shows one dll file. Now what to do with that dll. Can some one guide me as I am a complete beginner. I have windows 10 running on my PC

EDIT 1
Some people are in so much hurry to give negative points. May be some people want to see code snippet even for this question. Huh!

EDIT 2
Anyways I tried below and IT DID NOT WORK

This is how my notepad ++ looks like after installing them.

EDIT 3
Ok I fixed the issue. The problem is if you select multiple plugins together
(multiple checkboxes) and install them there seems to be some issue with notepad++, so the solution for me was to install the plugin individually.

Answer

You have to use the plugin manager of Notepad++ and search for the JSON plugin. There you can easily install it.
