The UPPER function to convert a normal text into upper case text.
In simple words, it converts a normal text case into a text in which all the letters are in upper case. For example, “excelchamps” will be converted into “EXCELCHAMPS”.
As I said, in an upper case text we have all the letters in capital form.
In the below example, we have used the upper function to convert name text to capital letters from the text in which characters are in different cases.
