About JSONView
JSONView
View JSON documents in the browser
Firefox has a built in JSON viewer, but it didn't always. JSONView was built to display JSON documents in an easy to read format, which is still nice if you don't like the default viewer. The document is formatted, highlighted, and arrays and objects can be collapsed. Even if the JSON document contains errors, JSONView will still show the raw text.
