What is a regular expression and how to use it? From where we can access it?

@Sarthak1

Regular expression matches the String value of an input field against a text pattern defined by a regular expression. Optionally, you can use the regular expression to extract particular substrings from the input text field matching a portion of the text pattern into new output fields. This is known as “capturing”.

You will get plugin **Regex Evaluation** in process studio.
