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.

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...

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

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.

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.

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.

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.

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.

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

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.
