Please give me a solution for this issue. Thanks in advance.

@EvilP I already validated this json in jsonlint.com and it gives valid json message. — Atul Patel

@AtulPatel then there is nothing wrong with your json itself, considered some manipulation that is done, or that could change your json ? — mas-designs
– mas-designs, Commented Mar 13, 2012 at 13:37
you say you validate it, then post invalid json that doesn't validate... what solution do you expect?? — charlietfl
– charlietfl, Commented Mar 13, 2012 at 13:42
your json string is valid. check with the code which will deal with manipulating the json results. is there any code you have written for retrieving the values of json string? — mini

you can replace \n with \\n for example

yourJsonText = yourJsonText.Replace("\n","\\n");

but if you use asp.net , it's better to encode your json string by

yourJsonText = HttpUtility.JavaScriptStringEncode(yourJsonText)

It's the
http://bit.ly/jJa131 sdfdsfasd shankar (shankar) part(s)

If you take that OUT (in both parts of the JSON) and pass it to jsonlint.com, the json validates succesfully.

Thanks for your reply. Actually my json string for this parts in single line due to i have copied in clip board. So this is a not part of this issue. because i already validate this json on jsonlint.com.

if jsonlint says it's valid then it's probably valid - perhaps your calling code encodes/decodes it incorrectly?

I wrote var obj = jQuery.parseJSON(msg.d); this line to parse this json string and it gives an error. msg.d returns this json string.

Well I just had the same error and after some debugging, I noticed that, there was a newline in one of the strings which was throwing the above error. I actually had it at the end of the string just before the quote.

{"One":"My String \n"}

Usually, those error can caused by string literals like:

\r\n

Be sure you properly encode this kind of literals if you use javascript's JSON.parse() function
