Which activity can split a string into an array in UiPath?

The correct choice is the Split string activity because it is specifically designed for dividing a given string based on a specified delimiter, resulting in an array of substrings. This activity allows users to input a string and choose a delimiter, such as a comma, space, or any character, which defines how the string will be split. The outcome is an array containing the different segments of the original string, making it easy to manipulate or access individual parts of the string later in the workflow.

In contrast, other options do not serve the same purpose. The Text to array activity is not a standard activity in UiPath for string manipulation. Similarly, the String manipulation activity is a broader term and may refer to various actions that can be performed on strings, but it does not specifically relate to splitting strings into arrays. Finally, the Assign activity is used to assign values or results to variables but does not inherently perform string splitting functions.
