Then put it in chrome web store :) I love this app but would love to be able to use it while offline too

would format the given JSON passed in the data query param

When the user presses the 'sort' button, the object is sorted on key.

This does not - of course - make a difference for the way the browser treats the object, but it makes it much more readable for the human eye.

It would be very, very helpful if there was an option to convert JS object style JSON to the stricter interpretation where all properties must be quoted as strings, e.g.

{
myprop: "my value"
}

becomes

{
"myprop" : "my value"
}

Paste multiple JSON line at once (separated with at least one line feed)

each of them processed as if i entered them separately

With a complex hierarchy, sometimes it would be really handy to compare two json objects in some color coded diff or something.

It would be crazy awesome if you could submit the form by hitting the enter key on the keyboard instead of having to hit the "Process" button all the time. I often test my JSON using the JSON Data:
JSON Data URL field instead of the blog text field.

Create a link that will show the output of the validator for an hour or so on a pastebin type link.

Xml-style, it's useful when you have pretty complex objects and you don't want to check it all

I use this tool all day every day, and just noticed sometime in the last few days it has gotten VERY slow - the "Valid" frame appears, but it takes forever for the formatted output to appear. Just a heads up! Great great tool!

Allow for the input window to show as in the output window.

I'm using Newtonsoft.Json to communicate with web API's but the returned string are always formatted with a "\" character before each <">
This makes the transformation of a formatted query to a use-able query quite bothersome (I have to manually remove each "\" before each <">)

it would be great to be able to share the results of a format request on line. Having the JSON Formatter store JSON data is probably out of scope for the service, but providing a link to a url and generating the formatted results for sharing would be a great stand-in.
