There are some great Chrome extensions around for pretty-printing JSON (great SU question here: Google Chrome Plugin for JSON Reading), but they all seem to depend on detecting whether the incoming document is in a JSON format automagically. So, the question is, how can I set it up so that I can pretty-print displayed JSON manually, rather than relying on some extension's magical detection (that may or may not fail to trigger when I need it to)?

I started from that SU post, and found a bootload of extensions:

(i.e., the results for JSON formatter). Those, and more, will all detect JSON formatting, and display it in a pretty-printed way, but none of them support an easy, bugproof way to manually turn it on on a page where JSON is not detected (except by, perhaps, tricking the engine by sticking format=json in the query string, but none of them were explicit about telling me I could do that). Is there a better option out there?

We don't do product recommendations unless prior research is shown ( please list the tools you have tried. I'd need to flag this as not useful. If you turn your question into "How can I do X?" it likely won't be deleted. Act now. – user 99572 is fine Mar 5 '13 at 20:42
Modified, thoughts? – A. Wilson Mar 5 '13 at 23:16
From the closing: "We expect answers to be supported by facts, references, or specific expertise, but this question will likely solicit debate, arguments, polling, or extended discussion." It seems like the question, "Is there a plugin that allows pretty-printing to manually be enabled" is pretty straightforward, and easy to support with reference. Am I missing something here? – A.

Your question was reopened. – user 99572 is fine Mar 6 '13 at 21:57
That would make sense if the question didn't start with "How", but it does start that way, so I don't understand your reasoning. – A. Wilson Sep 29 '15 at 4:28

I feel like a big dummy. Some more thorough searching turned up, which is exactly what I need.

That extension is not open source, and hasn't been maintained since 2013. JSON Formatter is actively maintained, better rated, and open source. – Dan Dascalescu Nov 24 '15 at 23:58
