JSON Editor
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, Edge.
Continuous integration tests are run on GitHub Actions, and LambdaTest is used to test on all major browsers.
Thanks, GitHub Actions and LambdaTest for the generous support for this open source project!
Successor: svelte-jsoneditor
This library jsoneditor has a successor: 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.

Documentation
Install
with npm (recommended):
npm install jsoneditor
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.jsandjsoneditor/dist/jsoneditor.min.cssto match the place where you've downloaded the library, or fill in the URL of the CDN you're using.
1<!DOCTYPE HTML> 2<html lang="en"> 3<head> 4 <!-- when using the mode "code", it's important to specify charset utf-8 --> 5 <meta charset="utf-8"> 6 7 <link href="jsoneditor/dist/jsoneditor.min.css" rel="stylesheet" type="text/css"> 8 <script src="jsoneditor/dist/jsoneditor.min.js"></script> 9</head> 10<body> 11 <div id="jsoneditor" style="width: 400px; height: 400px;"></div> 12 13 <script> 14 // create the editor 15 const container = document.getElementById("jsoneditor") 16 const options = {} 17 const editor = new JSONEditor(container, options) 18 19 // set json 20 const initialJson = { 21 "Array": [1, 2, 3], 22 "Boolean": true, 23 "Null": null, 24 "Number": 123, 25 "Object": {"a": "b", "c": "d"}, 26 "String": "Hello World" 27 } 28 editor.set(initialJson) 29 30 // get json 31 const updatedJson = editor.get() 32 </script> 33</body> 34</html>
Build
The code of the JSON Editor is located in the folder ./src. To build
jsoneditor:
-
Install dependencies:
npm install -
Build JSON Editor:
npm run buildThis 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:
npm startThis will update
./jsoneditor.jsand./jsoneditor.cssin the dist folder on every change, but it will NOT update the minified versions as that's an expensive operation.
Test
Run unit tests:
npm test
Run code linting (JavaScript Standard Style):
npm run lint
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
