I'm formatting string using this approach: How can I beautify JSON programmatically?

and then just call

textarea.setValue(formattedJson);

Is it poosible to get correctly formatted string in the textarea?

Answer 1

The JSON.stringify method takes Object as parameter. You probably send string as parameter. This is correct code:

jsonObj = {a: 'b', c: [1,2,3]};
// note that jsonObj is object, not string
jsonString = JSON.stringify(jsonObj, null, '\t');

textarea.setValue(jsonString);
