How to reformat JSON in Notepad++?

JsonParsingNotepad++

Json Problem Overview

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 https://stackoverflow.com/questions/46301700/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()"
        }
      ]
    }
  }
}

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

  1. Open Menu Plugins > Plugins Admin...

  2. Search JSON Viewer

  3. Check JSON Viewer in List

  4. Click on Install Button

  5. Restart Notepad++

  6. Select JSON text

  7. Go to Plugins > JSON Viewer > Format JSON ( Ctrl + Alt + Shift + M )

We can install any Notepad++ supported plugins using Plugins Admin...

Solution 3 - Json

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

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

enter image description here

Solution 4 - 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.

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()";
            }
            ];
        }
    }
}

As per the latest notepad++, updated answer. Install JSON Viewer

Solution 7 - Json

simply go to this link download the dll copy and paste the dll to the plugins folder at notepad++, \Notepad++\plugins restart the notepad++, and it should be shown in the list

jsformatter

NOTE: this dll supports 64 bit notepade++

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.

Solution 9 - Json

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

  1. Open Visual Studio
  2. File -> New -> File
  3. Select Web in left side panel
  4. Select JSON
  5. Copy paste your raw JSON value
  6. Press Ctrl + K and Ctrl + D

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

Solution 11 - Json

JSMinNpp plugin will do this job. https://sourceforge.net/projects/jsminnpp/

Solution 12 - Json

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

Solution 13 - Json

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:

> 1. Paste the file "NPPJSONViewer.dll" to Notepad++ plugin folder > 2. open a document containing a JSON string > 3. Select JSON fragment and navigate to plugins/JSON Viewer/show JSON Viewer or press "Ctrl+Alt+Shift+J" > 4. 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.

Solution 14 - Json

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.

Solution 15 - Json

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).

Solution 16 - Json

I'm using the JSON Viewer plug-in with NPP 5.9 and it seems to work well.

Solution 17 - Json

I know this thread is old but I recently ran into a problem with JSToolNPP not being compatible with my newly updated N++, I did find a replacement that seems to work. http://sourceforge.net/projects/nppjsonviewer/

Use at your own risk, ofc. (standard disclaimer from me when linking anything outside the SExchange, fyi)

Solution 18 - Json

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.

Solution 19 - Json

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.

Solution 20 - Json

I use 32-bit Notepad++ version 7.5.6. I have found that 32-bit JSToolNpp 1.20.0 does a great job.
The direct link is:
https://sourceforge.net/projects/jsminnpp/files/Uni/JSToolNPP.1.2006.0.uni.32.zip/download
which is redirected from https://sourceforge.net/projects/jsminnpp/.

JSON-Viewer works fine too, but cannot sort the JSON data.

Solution 21 - Json

You can use http://www.jsonlint.com/ to edit your json online if you don't have Notepad++.

Solution 22 - Json

I know you asked about NotePad++ but TextMate for OS X can do it via the JSON bundle, its called the "Reformat Document" command.

Solution 23 - Json

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.
