What is the purpose of using the Substring function in string manipulation?

Using the Substring function in string manipulation is primarily aimed at extracting a portion of a string. This function allows users to specify the starting position and the length of the substring they want to retrieve, making it an essential tool for handling text when only a part of the string is necessary for further processing. For instance, if you have a string that contains a full name but only need the first name, the Substring function can help you isolate just that segment of the string.

This capability is particularly useful in various scenarios, such as when formatting data, parsing inputs, or extracting specific information from larger texts. By using the Substring function effectively, you can efficiently manage and manipulate strings to meet your automation needs.
