Structure

In the Structure tab, the JSON data structure for the selected column is displayed. The structure or the Data Guide table must be generated in the parent source node, for example, Data Source node. If the structure is not found, then a message is displayed to communicate the same.

The following information about the data structure is displayed:

• JSON Attribute: Displays the generated JSON structure in a hierarchical format. You can select one or more attribute to import. When you select a parent attribute, all child attributes are automatically selected.

• JSON Data Type: Displays the JSON data types of all attributes, derived from JSON data.

• Unnest: All attributes inside an array are unnested in a relational format. By default, the Unnest option is enabled. When the Unnest option for an array attribute is disabled, then:

  • The child attributes are displayed but cannot be selected.

  • If the array attribute is selected for output, then the output column will contain JSON representation of the array.
