Extracts characters, digits or complete strings of a selected column to a new column using a regular expression (Regex).
The Processor is able to operate on any dataset. Nevertheless, it makes sense for the target column to contain string values.
The output of the Extract Regex Processor is the original dataset with an additional column that contains the extracted pattern.
The used regular expression selects the words that start with a capital letter in a given input text (more precisely, select the substring that starts with a capital letter).
