Description
-----------

Returned by :ref:`JSON.parse<class_JSON_method_parse>`, ``JSONParseResult`` contains decoded JSON or error information if JSON source not successfully parsed. You can check if JSON source was successfully parsed with ``if json_result.error == OK``.

Property Descriptions

.. _class_JSONParseResult_property_error:

- :ref:`Error<enum_@GlobalScope_Error>` **error**

+----------+------------------+
| *Setter* | set_error(value) |
+----------+------------------+
| *Getter* | get_error()      |
+----------+------------------+

The error type if JSON source was not successfully parsed. See :ref:`@GlobalScope<class_@GlobalScope>` ERR\_\* constants.

.. _class_JSONParseResult_property_error_line:

- :ref:`int<class_int>` **error_line**

+----------+-----------------------+
| *Setter* | set_error_line(value) |
+----------+-----------------------+
| *Getter* | get_error_line()      |
+----------+-----------------------+

The line number where the error occurred if JSON source was not successfully parsed.

----

.. _class_JSONParseResult_property_error_string:

- :ref:`String<class_String>` **error_string**

+----------+-------------------------+
| *Setter* | set_error_string(value) |
+----------+-------------------------+
| *Getter* | get_error_string()      |
+----------+-------------------------+

The error message if JSON source was not successfully parsed. See :ref:`@GlobalScope<class_@GlobalScope>` ERR\_\* constants.

.. _class_JSONParseResult_property_result:

- :ref:`Variant<class_Variant>` **result**

+----------+-------------------+
| *Setter* | set_result(value) |
+----------+-------------------+
| *Getter* | get_result()      |
+----------+-------------------+

A :ref:`Variant<class_Variant>` containing the parsed JSON. Use typeof() to check if it is what you expect. For example, if JSON source starts with curly braces (``{}``) a :ref:`Dictionary<class_Dictionary>` will be returned, if JSON source starts with braces (``[]``) an :ref:`Array<class_Array>` will be returned.

*Be aware that the JSON specification does not define integer or float types, but only a number type. Therefore, parsing a JSON text will convert all numerical values to float types.*

Note that JSON objects do not preserve key order like Godot dictionaries, thus you should not rely on keys being in a certain order if a dictionary is constructed from JSON. In contrast, JSON arrays retain the order of their elements:*

::

    var p = JSON.parse('["hello", "world", "!"]')
    if typeof(p.result) == TYPE_ARRAY:
        print(p.result[0]) # prints 'hello'
    else:
        print("unexpected results")
