What functionality do UpperCase(), LowerCase(), and TitleCase() provide?

1. Change string format to JSON

2. Check for spelling errors in a string

3. Transform a string to different case formats

4. Split a string into an array

The correct answer is: Transform a string to different case formats

UpperCase(), LowerCase(), and TitleCase() are functions specifically designed to manipulate string data by transforming its case. UpperCase() converts all characters in a string to uppercase, LowerCase() converts all characters to lowercase, and TitleCase() capitalizes the first letter of each word in a string while making all other letters lowercase. This functionality is fundamental in text processing, allowing users to standardize text formats, which is essential for tasks such as generating reports, preparing data for analysis, or ensuring consistency in string representation. The other options do not align with the core purpose of these functions. Changing string format to JSON, for instance, involves formatting data in a specific structure suitable for data interchange, which is unrelated to case transformation. Checking for spelling errors pertains to text validation and is not within the scope of case transformation functions. Similarly, splitting a string into an array is a different task that focuses on separating text, rather than transforming its case. Thus, the correct answer is that these functions transform a string to different case formats.
