Transform

The Transform Data Operation is an incredibly flexible operation with a wide variety of uses. It runs a single Airscript expression and saves the result to an output Variable. One common use case is to process the data from an HTTP Request and save it in Object-Service.

Use Cases

  • Process data from an API request to parse out only the relevant data for the rest of the Data Flow to consume.
  • Set an initial state for a Variable. For instance, you could set the initial value of a Variable called urlby using the Transform Expression "google.com"with urlas the name of the Transform's result.
  • Use a Query Expression to easily parse information from a list.
  • Set a default value for a Variable that might be NULL. For instance, you could use this Airscript expression to default to "No Name" if the name Variable is NULL:
    IF(name = NULL, "No Name", name)
  • Set up a Variable to reuse throughout the rest of the Data Flow. For instance, to easily use a URL in several HTTP Request steps, you could set the URL to a Variable with a Transform step.
