Agenty allows to add built-in Post-Processing functions with result field to easily clean, manipulate the agents field result. For example, if you have a "Price" field in your agent with dollar($) symbol but don't want that symbol in your agent result, you can use the built-in Replace function to replace the "$" with blank "" by passing the parameters.
There are many function available in Agenty, to use by passing the different parameters available on each function to manipulate the field result.
The post-processing function executes in parallel for each input URL while the agent is running. So, when a post-processing function is enabled, you will see the processed result by-default in your result table. While the Post-Processing feature in Scripting run after the agent job is completed and keeps both the result "Original" and "Modified" accessible on portal or via API.
