I would also recommand js2-mode.

JSON stands for JavaScript Object Notation. It's not another language and it's even not a data container like yaml or xml are. JSON could be used as a data container if there's no function (or in this case we should say method) inside a JSON object, but it's not the primary goal of JSON :-)

<pre><code>var myJSObject = {
 attr: {foo: "bar", baz: ["quux", "truc", "pouet"]},
 fooAlert: function (num) {
 alert(this.attr.foo+' '+num);
 }
};
myJSObject.fooAlert(42);
</code></pre>

If you want something lightweight try this major-mode I hacked together: <a href="https://github.com/joshwnj/json-mode" rel="noreferrer">https://github.com/joshwnj/json-mode</a>

It's actually no more than some extra syntax highlighting on top of javascript-mode, but for my purposes I've found it to work quite well.

Another common use-case is auto-formatting a JSON file (eg. if it's whitespace-compressed and you want more readability). To do this I'm just piping the buffer through a command-line script: C-u M-|

Since JSON is a subset of YAML, <code>yaml-mode</code> works too (I don't know how it compares to <code>js-mode</code> and <code>json-mode</code>, though).

Install (from emacs): <code>M-x package-install yaml-mode</code>.

I will also second Josh's json-mode, but also recommend flymake-json as an addition. It helps highlight syntax errors.

I don't like using <code>python -mjson.tool</code> because it reorders items in JSON objects.
I find <code>(prog-indent-sexp)</code> works just fine to reindent, and using <code>jsonlint</code>
instead of <code>python -mjson.tool</code> works for pretty printing/reformatting in <code>beautify-json</code>

I've expanded on Mariusz Nowak's <a href="https://stackoverflow.com/a/5841588/1713079">workaround</a>, to make it usable as a major mode in its own right. Little modification was required beyond simply deriving the mode; the only change Nowak's work actually needed was the ability to recognize buffers not associated with files, or associated with files whose names don't end in <code>.json</code>, as JSON, which we accomplish with a buffer-local variable.

Here's the augmented workaround:

<pre><code>(make-variable-buffer-local 'js2-parse-as-json)

(defadvice js2-reparse (before json)
 (setq js2-buffer-file-name buffer-file-name))
(ad-activate 'js2-reparse)

(defadvice js2-parse-statement (around json)
 (if (and (= tt js2-LC)
 js2-buffer-file-name
 (or js2-parse-as-json
 (string-equal (substring js2-buffer-file-name -5) ".json"))
 (eq (+ (save-excursion
 (goto-char (point-min))
 (back-to-indentation)
 (while (eolp)
 (next-line)
 (back-to-indentation))
 (point)) 1) js2-ts-cursor))
 (setq ad-return-value (js2-parse-assign-expr))
 ad-do-it))
(ad-activate 'js2-parse-statement)

(define-derived-mode json-mode js2-mode "JSON"
 "Major mode for editing JSON data."
 :group 'json
 (setq js2-parse-as-json t)
 (js2-reparse t))

(add-to-list 'auto-mode-alist '("\\.json$" . json-mode))
</code></pre>

If you already use js2-mode, this may be a better option than <code>js-mode</code> plus <code>flymake-json</code> because you need not install anything new (js2-mode already does syntax checking, no need for an external tool), and because this mode will inherit your js2-mode configuration, which js-mode will not.

<code>json.el</code> by Edward O'Connor is part of GNU Emacs since 23.1 (2008).

While it isn't a syntax highlighter, it has a useful function to format JSON:

<pre><code>M-x json-pretty-print-buffer RET
</code></pre>

So, if you have a recent version of Emacs, there is no need for <code>jq</code> or <code>python -m json.tool</code>.

Does anybody know a good Emacs mode to edit JSON? An app I am working on uses a JSON based communication protocol and having the data nicely indented and syntax-highlighted would help me a lot in the process of figuring it out.

有谁知道一个好的Emacs模式来编辑JSON吗？我正在开发的一个应用程序使用了基于JSON的通信协议，将数据进行良好的缩进和语法突出显示将对我在弄清楚它的过程中帮助很大。
