What does the TRIM function do in Excel?

The TRIM function in Excel is specifically designed to enhance text management by removing extra spaces from strings. It clears out leading and trailing spaces, as well as any excess spaces that appear between words, reducing them to a single space. This is particularly useful for cleaning up data that may have been imported from other sources where formatting inconsistencies commonly occur.

For example, if you have the text " Hello World ", using the TRIM function on this text would produce "Hello World" as the output, effectively maintaining only the necessary single space between "Hello" and "World". This function does not alter the words themselves or change the case; its sole purpose is to tidy up space usage, making it an essential tool for preparing data for analysis or presentation.
