What function can be used in Alteryx to convert a string to uppercase?

The function used to convert a string to uppercase in Alteryx is specifically designed as Upper(). This function takes the input string and transforms all lowercase characters to their uppercase equivalents. It is concise and efficient, making it an ideal choice for this operation within the Alteryx environment.

The other options, while they may seem like plausible alternatives, do not exist in Alteryx. For example, Capitalize() implies a function that may capitalize the first letter or make a string title case but does not specifically address conversion to uppercase. Similarly, ToUpperCase() and StringToUpper() are not recognized functions in Alteryx, which means they would not work if used in a workflow. Therefore, Upper() is the accurate and appropriate function for converting strings to uppercase within Alteryx.
