How to reformat JSON in Notepad++?

Question

I need Notepad++ to take a json string from this

{\"menu\": {\"id\": \"file\",\"value\": \"File\",\"popup\": {\"menuitem\": [{\"value\": \"New\", \"onclick\"         


        

Answer 1

The following Notepad++ plugin worked for me as suggested by "SUN" https://sourceforge.net/projects/jsminnpp/

Answer 2

It worked for me in the latest edition to Notepad using the UniversalIndentGui.

What I did was under the plugin setting choose Enable Text Auto Update, a window popped up and I selected javascript.

Answer 3

Notepad 5.8.7 and jsmin 1.7.0.0 works wonderful here.

Be careful though, found out jsmin eats the comments the hard way (should have read first).

Answer 4

Your best bet is to use one of the latest versions of Eclipse (I am using Eclipse Galileo J2EE and Eclipse Ganymede J2EE). Create a JavaScript file, then create a variable:

var jsonObject = {"menu": {"id": "file","value": "File","popup": {"menuitem": [{"value": "New", "onclick": "CreateNewDoc()"},{"value": "Open", "onclick": "OpenDoc()"},{"value": "Close", "onclick": "CloseDoc()"}]}}};

Lastly, hit CTRL+SHIFT+F and voila! You have a nicely indented JSON Object. I, too, am looking for a Notepad++ JSON formatter, and I very well may be forced to develop an Npp plugin some short time in the future.

Answer 5

Update:

As of Notepad++ v7.6, use Plugin Admin to install JSTool per this answer

INSTALL

Download it from http://sourceforge.net/projects/jsminnpp/ and copy JSMinNpp.dll to plugin directory of Notepad++. Or you can just install "JSTool" from Plugin Manager in Notepad++.

New Notepad++ install and where did PluginManager go? See How to view Plugin Manager in Notepad++

{
  "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.

Universal Indent GUI plugin for Notepad++ will turn your sample into:

{
    "menu" : {
        "id" : "file", "value" : "File", "popup" : {
            "menuitem" : [ {
                "value" : "New", "onclick" : "CreateNewDoc()";
            }
            , {
                "value" : "Open", "onclick" : "OpenDoc()";
            }
            , {
                "value" : "Close", "onclick" : "CloseDoc()";
            }
            ];
        }
    }
}
