JSON formatting

Sometimes it is needed to format JSON to check it's content. Intellij IDEA and Eclipse do the job pretty well, but if these are not available it is easily possible in Google Chrome. To do it:
1) Go to Control the current page menu (document icon to the left of address input) then Developer/JavaScript console.
2) Enter console.log({qwe:123}) (where {qwe:123} is just any JSON object).
3) You got nice JSON object tree as output.
There is some noise from Chrome, but it is possible to see and browse your object.
Same feature is in Firefox with Firebug plugin, even the same syntax.
