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

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

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

+----------+-----------------------+
| *Getter* | get_error_line() |
+----------+-----------------------+
The line number where the error occurred if JSON source was not successfully parsed.

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")
