UPPER

The UPPER function converts a text string to all uppercase letters. UPPER function takes just one argument, text, which can be a text value or cell reference. UPPER changes any lowercase characters in the text value to uppercase. Numbers, punctuation, and spaces are not affected. UPPER will convert numbers to text with number formatting removed. Numbers or punctuation characters inside a text string are unaffected: If a numeric value is given to UPPER, number formatting is removed. For example, if cell A1 contains the date June 26, 2021, date formatting will be lost and UPPER will return a date serial number as text: If necessary, you can use the TEXT function to workaround this limitation. Use TEXT to convert the number to a text value, then pass that value into UPPER: Use the LOWER funct
