What is the purpose of the LOWCASE function?

The LOWCASE function is specifically designed to take a character string as its argument and convert all the characters within that string to their lowercase equivalents. This function is particularly useful when you want to standardize text data for comparison or formatting purposes, ensuring consistency across datasets, especially when dealing with user input or text that may come in various cases.

For example, if you have a string that contains both uppercase and lowercase letters and you want to ensure they are all in lowercase for consistent searching or reporting, applying the LOWCASE function will achieve that.

The other options focus on different functionalities that are not related to the purpose of the LOWCASE function. Capitalizing the first letter of each word describes a different process altogether, while removing consecutive blanks or searching for substrings relates to string manipulation and search functions, which are not the aim of the LOWCASE function.
