Which function capitalizes the first letter in each word of a string?

The function that capitalizes the first letter in each word of a string is indeed the PROPCASE function. This function is particularly useful when you want to format text appropriately, ensuring that each word begins with an uppercase letter while the rest of the letters in each word are converted to lowercase. For instance, if you have a string like “hello world”, using the PROPCASE function will transform it to “Hello World”.

This function is commonly used in data preparation and reporting to enhance the readability of text data, especially in scenarios where consistency in capitalization is critical, such as preparing names or titles for presentation.

In contrast, the other functions listed serve different purposes. For example, FIND is used to locate the position of a substring within a string, LOWCASE changes all characters in a string to lowercase, and COMPRESS removes specified characters from a string. Understanding these distinctions underscores why PROPCASE is the correct choice for achieving proper capitalization in text strings.
