The Substring action is used to select or manipulate a specific substring in a text (string). It can be thought of as an operation to get a specific range or sequence of characters in a text.
It is the process of selecting a specific range or characters of a text. For example, if we want to get the word ‘Hello’ as a substring in the expression ‘Hello World’, substring (‘Hello World’, 0, 5) must be entered.
The substring action is a specialised version of the subarray action, that is, it takes only string values.
