Excellent tool! It does exactly what it says and it does it so well! Thanks! Tip: if yours is not working try disabling other plugins that are running. In my case, Ghostery was causing a problem, I disabled it and bang, it works great!
This plugin does what it says, and it does it very well, the problem is it returns all websites as JSON! Even when I select to work only on click OR select to work on specific websites only, yet it doesn't care about my settings and return all sites as JSON!
It's very handy. It would be nice to handle "file://" on clickable urls
I tried the JSON Viewer extension first, and while it did an acceptable job of formatting, JSON Formatter's formatting had more of a "native" look and behavior. Searching JSON content works just like searching any content in Chrome; whereas, JSON Viewer has implemented it's own search feature, which doesn't tell you the number of instances of the search term, or which one you're currently on. JSON Formatter works exactly like I expected it should.
super
It works but, I would like a dark mode.
This is the most efficient way that I've seen to test API and understand the structure of the JSON returned. I highly recommend this!
This is the best extension for Json formatting which i am looking for. I am love it.
really good !
It is very useful for formatting json data. But it does not work for very big json data.
