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.
Knowing that, 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 some 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?
