Transform Node
The Transform node in Cobalt empowers users to manipulate and transform complex JSON data into a more accessible format using JSONata expressions. This versatile node streamlines data processing and enables users to extract specific information or perform custom transformations on JSON objects within workflows.

Input Fields
The Transform node offers two input fields:
Please note that both the input and query fields are required for the Transform node to function properly.
Input
This field accepts a JSON object, where the Array needs to be given and can be selected from a DataSlot or a previous Node in the workflow. It serves as the input data for transformation. The format of the Input can be in the format:
{
"input": "{Array_name}" // When you have the Array
"input": "{{Node_name: data}}" // When you want to fetch response of a previous node.
// The Node_name is selected by using Nodes in Variables
// "input" and "data" key can be replaced by any other word like result etc.
}
Query
In this field, users need to provide a valid JSONata expression to query or transform the input object. The expression structure in Query is given below.
{
"output": "JSONata expression"
// The key should be "output" in Query field.
}
If only the JSONata expression is provided in Query field rather than an object, then the node will give an empty response and result cannot be used in further nodes of the Workflow.
Node Rule Conditions
The Transform node also supports Node Rule Conditions, allowing users to define conditions under which the transformation should occur. This provides additional control and flexibility in workflow execution based on specific criteria.
By leveraging the Transform node in Cobalt workflows, users can efficiently process and manipulate JSON data, enabling seamless integration and automation of data-driven processes. Whether extracting specific information or performing complex transformations, the Transform node offers a powerful tool for managing JSON data within workflows.
