JSON editor/formatter?

Answer 1

Have you tried this?

http://jsonformat.com/

Answer 2

I use http://curiousconcept.com/jsonformatter to format computer generated jsons. It makes it much readable.

Answer 3

Remember that JSON is just a Javascript Object Literal with fancy clothes. You should be able to use any Javascript Beautifier to clean it up.

Answer 4

You can download http://www.thomasfrank.se/json_editor.html and run it locally on your own data, although it is an editor rather than a formatter.

http://www.jsonlint.com/ is also a useful validation and reformatting tool.

Answer 5

If you need a desktop json editor i could prefer JSONpad (JSON Editor/Viewer/Formatter for Adobe Air Runtime)

http://www.jsonpad.co.cc

Answer 6

On windows I go for: http://jsonviewer.codeplex.com/

Handy for pulling raw JSON responses from Firebug and parsing it for me.
