JSON Editor is a web-based tool to view, edit, format, and validate JSON. It has various modes such as a tree editor, a code editor, and a plain text editor. The editor can be used as a component in your own web application. It can be loaded as CommonJS module, AMD module, or as a regular javascript file.

The library was originally developed as core component of the popular web application https://jsoneditoronline.org and has been open sourced since then.

Supported browsers: Chrome, Firefox, Safari, Opera, Edge, Internet Explorer 11.

Successor: svelte-jsoneditor


This library [jsoneditor](https://github.com/josdejong/jsoneditor) has a successor: [svelte-jsoneditor](https://github.com/josdejong/svelte-jsoneditor). The new editor is not a one-to-one replacement, so there may be reasons to stick with jsoneditor.
The main differences between the two are described here.

Install


with npm (recommended):

    npm install jsoneditor

Note that to use JSONEditor in Internet Explorer 11, it is necessary

to load a polyfill for Promise in your application.


Alternatively, you can use another JavaScript package manager like https://yarnpkg.com/, or a CDN such as https://cdnjs.com/ or https://www.jsdelivr.com/.

Use


Note that in the following example, you'll have to change the urls jsoneditor/dist/jsoneditor.min.js and jsoneditor/dist/jsoneditor.min.css to match the place where you've downloaded the library, or fill in the URL of the CDN you're using.


  1. ``` html
  2. <!DOCTYPE HTML>
  3. <html lang="en">
  4. <head>
  5.     
  6.     <meta charset="utf-8">
  7. <link href="jsoneditor/dist/jsoneditor.min.css" rel="stylesheet" type="text/css">

  10. <body>
  11.     <div id="jsoneditor" style="width: 400px; height: 400px;"></div>
  12. <script>
  13.         // create the editor
  14.         const container = document.getElementById("jsoneditor")
  15.         const options = {}
  16.         const editor = new JSONEditor(container, options)

  24.             "String": "Hello World"
  25.         }
  26.         editor.set(initialJson)
  27.         // get json
  28.         const updatedJson = editor.get()

Build


The code of the JSON Editor is located in the folder ./src. To build
jsoneditor:

- Install dependencies:

  1. ```
  2.   npm install
  3. ```

- Build JSON Editor:

  1. ```
  2.   npm run build
  3. ```

  This will generate the files ./jsoneditor.js, ./jsoneditor.css, and  
  minified versions in the dist of the project.

- To automatically build when a source file has changed:

  1. ```
  2.   npm start
  3. ```

  This will update ./jsoneditor.js and ./jsoneditor.css in the dist folder
  on every change, but it will NOT update the minified versions as that's
  an expensive operation.

Test


Run unit tests:

  1. ```
  2. npm test
  3. ```

Run code linting (JavaScript Standard Style):

  1. ```
  2. npm run lint
  3. ```

Custom builds


The source code of JSONEditor consists of CommonJS modules. JSONEditor can be bundled in a customized way using a module bundler like browserify or webpack. First, install all dependencies of jsoneditor:

    npm install

To create a custom bundle of the source code using browserify:

    browserify ./index.js -o ./jsoneditor.custom.js -s JSONEditor

The Ace editor, used in mode code, accounts for about one third of the total
size of the library. To exclude the Ace editor from the bundle:

    browserify ./index.js -o ./jsoneditor.custom.js -s JSONEditor -x brace -x brace/mode/json -x brace/ext/searchbox

To minify the generated bundle, use uglifyjs:

    uglifyjs ./jsoneditor.custom.js -o ./jsoneditor.custom.min.js -m -c
