plugins > plugins adminand install
(jstool is available on both 64 bit and 32 bit versions of notepad++)
after installing jstool, open up any unformatted .js file in notepad++ and go to
plugins > jstool > jsformat
here is a larger unformatted .js file (jquery compressed), if you need something to test on: https://code.jquery.com/jquery-3.3.1.min.js
(this is a good file for testing, as it has 86kb of code in just 3 lines, which will be expanded to readable 118kb in 4157 lines, after running jsformat)
note: i did not find any plugins, that are able to correctly format/indent mixed html and js code.
if you have mixed html/js files, you currently have to copy the js code part(s) to a new tab, run
plugins > jstool > jsformatfrom there, and then copy/paste the formatted js back to your mixed html/js file, replacing the unformatted js code part.
thanks it works!!!
