Reading JSON
Alteryx Designer can read and parse JSON in structured form through the Input Data tool starting from 24.1. For now, AMP Engine supports only one top level of nested objects.

Reading Data in Unstructured Form
The Input Data tool by default reads data in unstructured form.
AMP Only: Read Data in structured form checkbox - unselected.
Unstructured mode only: Parse Value as String checkbox - selected.
Output values into single string field: Two fields are output, JSON Name and JSON_ValueString. Looking at the input example above, the following data comes out of the tool:
JSON_Name | JSON_ValueString |
