Most probably you have exceeded MaxJsonLength, by default it is 102400 characters and your string is bigger. You can increase this limit in web.config:

<configuration>
    ... 
    <system.web.extensions>
        <scripting>
            <webServices>
                <jsonSerialization maxJsonLength="300000" />
            </webServices>
        </scripting>
    </system.web.extensions>
    ...
</configuration>
