Java - How to convert values within JSON String (remove quotes on non-strings)?

Question

I have a String, representing a JSON, e.g.

      {"someId":"2130706433","someValue":"Android","networkId":"0","someTag":"true", ...}

Now I want to remove the quotes, but only where I can (numbers and booleans). How do I best do this (in Java)?

Result should look like:

       {"someId":2130706433,"someValue":"Android","networkId":0,"someTag":true, ...}

Thanks for any help :)

Why don't you chose to convert it into an object using jackson or java api ? — Em Ae

Try parsing it into a JSONObject, and then truning it back to a String however you like. I prefer using JSONSimple but thats up to you to decide :- ) EDIT: There may be a suffisticated way to do it through regex's that i am not aware of. — fill͡pant͡

If I convert to an object, the problem is, since the values are quoted it is still recognized as a String, no matter what data type actually is in there — olkoza

You can do this with a fairly simple regex replace:

jsonString.replaceAll("\"([0-9]+|true)\"", "$1");

if every number and boolean in quotes is to be replaced.
