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": "CreateNewDoc()"},{"value": "Open", "onclick": "OpenDoc()"},{"value": "Close", "onclick": "CloseDoc()"}]}}}

to this...

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

I looked around at all the TextFX options but couldn't find anything that worked.

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.

The plugin still works for me as of Notepad v7.6.1. Try putting the DLL in its own plugin directory (i.e. `plugins/JSMinNPP/JSMinNPP.dll`) – Dan H Dec 14 '18 at 21:08
It will also minify, which is a nice feature. – Justin Braaten Jan 24 '19 at 18:59
@Prakash I guess you mean when you use it on a JSON that has an extension it doesn'trecognize as JSON, such as .txt or .mcmeta? Yeah, apparently it properly recognizes such files as JSON after you do anything JSTool with them. A neat and useful side effect. – Egor Hans Nov 01 '20 at 15:22

If JSTOOL and JSONVIEWER are not working, make sure the file is NOT opened from inside a .zip file. For some reason most plugins don't work correctly when the file is opened in windows from within a zip file. Just extract the file first, then open in NP++ and plugins will work fin. – JG1212 Feb 11 '21 at 16:29
It's the middle of 2022 and JSTOOL still works as intended! I was able to copy junky results of an API call to readable JSON. – CaptainGenesisX Jun 22 '22 at 18:36

For Notepad++ v.7.6 and above Plugins Admin... is available.

Open Menu Plugins > Plugins Admin...
Search JSON Viewer
Check JSON Viewer in List
Click on Install Button
Restart Notepad++
Select JSON text
Go to Plugins > JSON Viewer > Format JSON ( Ctrl + Alt + Shift + M )

You require a plugin to format JSON. To install the plugin do the following steps:

Open notepad++ -> ALT+P -> Plugin Manager -> Selcet JSON Viewer -> Click Install
Restart notepad++
Now you can use shortcut to format json as CTRL + ALT +SHIFT + M or ALT+P -> Plugin Manager -> JSON Viewer -> Format JSON

I personally use JSON Viewer since the Notepad++ plugin doesn't work any more.

EDIT - 24th May 2012

I advise that you download the JSMin plugin for Notepad as mentioned in the answer. This works well for me in the latest version (v6.1.2 at time of writing).

EDIT - 7th November 2017

As per @danday74's comment below, JSMin is now JSToolNpp. Also, please be aware that the JSON Viewer tool is on Codeplex which will likely disappear in the near future.

Given the above, this answer is no longer relevant and you should use Dan H's answer instead. My answer is simply here for posterity.

It's not an NPP solution, but in a pinch, you can use this online JSON Formatter and then just paste the formatted text into NPP and then select Javascript as the language.

If formatting JSON is the main goal and you have VisualStudio then it is simple and easy.

Open Visual Studio
File -> New -> File
Select Web in left side panel
Select JSON
Copy paste your raw JSON value
Press Ctrl + K and Ctrl + D

That's it. you will get formatted JSON Value.

You can view in Notepad++ no problem now (maybe older versions were bugged?)

for win64: You can find the latest plugin here: https://github.com/kapilratnani/JSON-Viewer/releases . The latest zip file contains a .dll file.

And then follow the github priject README instructions:

Paste the file "NPPJSONViewer.dll" to Notepad++ plugin folder

open a document containing a JSON string

Select JSON fragment and navigate to plugins/JSON Viewer/show JSON Viewer or press "Ctrl+Alt+Shift+J"

Voila!! if the JSON is valid, it will be shown in a Treeview

It should be the same process for win32 but I cannot personally verify it.

If you don't want to install a Notepad++ plugin but you have Firefox and a JSON plugin for Firefox, you can select Run -> Launch in Firefox. You get the contents formatted as JSON using your Firefox plugin.

This is what I personally do.

For those of us behind a corporate firewall with no direct access to the internet, using the Plugins Admin won't work. To use the JSMinNpp plugin, you can't just "copy the dll to the plugins folder". It needs to live inside a folder called "JSMinNpp" inside the plugins folder. After doing that and restarting Notepad++, I was able to see the "JSTool" menu option under the Plugins menu.

Tested with Notepad++ 7.8.2 and 7.8.9.

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.
