Remember that the LOWER function doesn’t affect numbers or special characters, it only converts alphabetical characters to lowercase.

Additional information

The LOWER function is a part of Excel’s arsenal of text manipulation functions, which can be particularly helpful when working with textual data. It’s a non-destructive function, meaning it doesn’t change the original text; it only provides a lowercase version of it. Whether you’re dealing with data cleaning, data analysis, or preparing text for other functions, LOWER can be a valuable tool.
