Let’s evaluate the parsing of each: http://jsfiddle.net/brandonscript/Y2dGv/ The tl;dr here: The fragment in the json2 variable is the way the JSON spec indicates null should be represented. But as always, it depends on what you’re doing — sometimes the “right” way to do it doesn’t always work for your situation. Use your judgement and make an informed decision. JSON1 {} This returns an empty … Read more
http://lloyd.github.com/yajl/ http://www.digip.org/jansson/ Don’t really know how they compare for speed, but the first one looks like the right idea for scaling to really big JSON data, since it parses only a small chunk at a time so they don’t need to hold all the data in memory at once (This can be faster or slower … Read more
Pretty-printing is implemented natively in JSON.stringify(). The third argument enables pretty printing and sets the spacing to use: If you need syntax highlighting, you might use some regex magic like so: See in action here: jsfiddle Or a full snippet provided below: Show code snippet

I get this error “uncaught syntaxerror unexpected token U” when I run my page in chrome. And in firefox I get, “JSON.parse: unexpected character”. I’m returning the json data from a php file and the returning json string is valid. I checked it with http://jsonlint.com/ . Any help would be appreciated… Thanks. Here’s the returned JSON string

Depending on the data you’re trying to get, I’d recommend using Yahoo’s YQL API for accessing Yahoo Finance (An example can be found here).
