Transform Node This node allows you to execute a transformation within a pipeline (custom Python code).

​
Node Inputs

Dynamic Inputs defined in the transformation.

​
Node Parameters

On the face of the node:
  1. Transformation: Select a transformation that you have created (or create a new one)
    • Type: Dropdown

​
Node Outputs

Dynamic Outputs defined in the transformation.

​
Examples

​
Example 1: Using a Transformation to display the date and time in formatted manner

​
Transformation

In this example, first we will create a transformation that formats the date and time in a human-readable manner. Create a transformation with the following parameters:
  • Function Name: format_date_time
  • Description: Formats the date and time in a human-readable manner
  • Inputs: date_time
  • Outputs: formatted_date_time
Transformation Example 1 In the code, the datetime module is used to format the date and time. 
def format_date_time(date_time):
    from datetime import datetime

    cleaned = date_time.replace(" / ", " ")
    date_obj = datetime.strptime(cleaned, "%d/%m/%Y %H:%M:%S")
    formatted_date_time = date_obj.strftime("%d %B %Y at %H:%M:%S")
    return {'formatted_date_time': formatted_date_time}
Note: The imports take place in the function definition. Also, it is a good practice to test the transformation in the editor before deploying the changes. To test the transformation, you can use the Test Code button in the top right corner of the editor accordion. Transformation Example 1 Test

​
Pipeline

In this example, we will use the transformation in a pipeline.
  1. Time Node: Gets the current date and time
  2. Transformation Node: Uses the transformation to format the date and time
    • Input: {{time_0.output}}
    • Transformation: Demo date time transformation
  3. Output Node: Displays the formatted date and time
    • Output: {{transformation_0.formatted_date_time}}

​
Example 2: Using a Transformation to convert a files content to base64 and output the first 10 characters

​
Transformation

In this example, we will create a transformation that converts the content of a file to base64 and outputs the first 10 characters. Create a transformation with the following parameters:
  • Function Name: file_to_base64
  • Description: Converts the content of a file to base64 and outputs the first 10 characters
  • Inputs: input_file
  • Outputs: base64_content
Transformation Example 2 In the code, the base64 module is used to convert the content of a file to base64. 
def file_to_base64(input_file):
    import base64
    import json
    file_content = base64.b64decode(input_file['content']) 
    base64_content = str(file_content)
    return {'base64_content': base64_content}
Also, it is a good practice to test the transformation in the editor before deploying the changes. To test the transformation, you can use the Test Code button in the top right corner of the editor accordion. Transformation Example 2 Test

​
Pipeline

In this example, we will use the transformation in a pipeline.
  1. Input Node: takes a file as input
  2. Transformation Node: Uses the transformation to convert the content of a file to base64
    • Input_file: {{input_0.file}}
    • Transformation: Demo File Transformation
  3. Output Node: Displays the base64 content of the file
    • Output: {{transformation_0.base64_content}}
