If you receive information from others as an odd assortment of upper- and lowercase characters, you may want to put the PROPER worksheet function to work for you. This function converts text so that the first letters of any words are uppercase and everything else is lowercase. Actually, what it does is make everything lowercase except any letters that do not follow another letter. Thus, any letters following spaces, punctuation, or numbers would be converted to uppercase.
As an example, if cell D4 contains “THIS IS MY TEXT”, you could use the following formula in cell E4:
The result is that cell E4 will contain “This Is My Text”.
