Use JSTool
As of Notepad++ v7.6, you can use the Plugin Admin option in Notepad++ to install JSTool.
Manual Install
- Download it from https://www.sunjw.us/jstool/npp/#download
- Copy JSMinNpp.dll to the plugin directory of Notepad++. You may need to create a directory named "JSMinNPP" in the plugin directory after version 7.6.3
Here's an example of JSON that's been formatted using the tool:
{
"menu" : {
"id" : "file",
"value" : "File",
"popup" : {
"menuitem" : [{
"value" : "New",
"onclick" : "CreateNewDoc()"
}, {
"value" : "Open",
"onclick" : "OpenDoc()"
}, {
"value" : "Close",
"onclick" : "CloseDoc()"
}
]
}
}
}

Tip: Select the code you want to reformat, then Plugins | JSTool | JSFormat.
