How to make parsing faster for large and complex JSON?

Question

I want to parse a large JSON. How can I make it faster? Now it takes a lot of time. Please help me.

Use a library that has been tested and optimized for that already. Why are you writing your own? — dchhetri, Dec 01 '12 at 04:38

you can use some wrappers like http://code.google.com/p/json-simple/ it is optimised to handle large data from json and easy to use.

Also you can give it try to http://code.google.com/p/json-simple/ for better performance.

Following are the others.

Android built-in: http://developer.android.com/reference/org/json/package-summary.html
JSON.simple: http://code.google.com/p/json-simple/
Jackson: http://jackson.codehaus.org/
Gson: http://code.google.com/p/google-gson/

You can check comparison article over here.

Use jackson JSON processor http://jackson.codehaus.org/ Most of the time people end up parsing the whole JSON and ignoring most of the data. This makes the process slow. If you are going to discard a lot of data, parsing in SAX mode is much faster, since you can stop parsing as soon as you have found all the required data.
