I'm trying to Serialize a string into JSON content but does not seems its JSON content and I have tried the following

Is there a way to convert to JSON format or you have do manually?

String jsonStr = '[image[1,2,3,4];image2:[2,23];image3:[3,4];image4:[true];image5:[true];image6:[true];]';

String JSONString = JSON.serialize(jsonStr);
system.debug('JSONString : ' +JSONString );

after executing the above in Anonymous Window I get the following result:

    What is your exact requirement? JSON.serialize method Serializes Apex objects into JSON content.

  • What would you expect the output string to be? You can deserialize into an appropriate object structure if you define one.

  • @DougB: I expect the output to be JSON format, I do not have any object, but I will be storing the json string into one of my custom field

It's not clear what the output String you are expecting is. The contents of the String are JSON so perhaps you are wanting to expand those into an object?

If you can express what you think the output string should look like, then we may be able to better help? You want an output that is a String, but somehow changed from the original String?

Perhaps you are looking for something like this

public class AWrapper{  
    String jsonStr;

aWrapper nickWrapper = new AWrapper();
nickWrapper.jsonStr = '[image[1,2,3,4];image2:[2,23];image3:[3,4];image4:[true];image5:[true];image6:[true];]';
String JSONString = JSON.serialize(NickWrapper);
system.debug('JSONString : ' +JSONString );

So the output looks like
