Which processing step allows for modifying parts of the input value in a placeholder?

The processing step that allows for modifying parts of the input value in a placeholder is the one associated with the extraction of specific data points. When using extraction, the focus is on identifying and isolating relevant data from a larger set of information. This can involve using regular expressions or other parsing techniques to capture particular elements of the input value, which can then be modified or transformed as needed.

For instance, if the input value is a string that contains various details, extraction lets you pull out just the segment you want to change, allowing for enhanced customization of the output. This is particularly useful in scenarios where logs or data need to be adjusted before being used for monitoring or reporting.

Other processing steps do not provide the same capability. While summarizing focuses on condensing information, logging captures data for future reference without alteration. The notify step is specifically for alerting based on certain conditions and does not involve modifying input values. Therefore, extraction stands out as the processing step that specifically enables modifications through targeted data capture.
