Step 2 Use one of the following text functions to change the case:
=UPPER(A2): Converts text to UPPERCASE.
=LOWER(A2): Converts text to lowercase.

=PROPER(A2): Capitalizes the first letter of each word.
In our case, we have typed the formula =PROPER(B2) in cell C2 and press Enter key.

You will see that all names now start with a capital letter and the remaining text is in lowercase.

Step 3 Copy the formula down the column to apply it to all rows.

Now, delete the column B, as it is no longer needed.
