I was recently shown the Best. Chrome. Extension. Ever.

JSONView is a Chrome extension that formats JSON when opened in Chrome. Normally when you hit a URL that returns JSON, Chrome displays a pile of goo. Actually, it just display the JSON as is, but most rendered JSON is not well formatted (and doesn’t need to be, it’s not intended for humans).

JSONView cleans up the formatting and applies syntax highlighting. Better still, it displays any errors it finds while parsing the JSON. If you are developing an API that sends JSON, it’s a great way to make sure what you are sending is valid and, when it’s not, to debug the problem.

It seems like everyone knew about this before me, but if you don’t, you just might want to add your tool box.
