Details

UPPER changes all lowercase letters to uppercase. Digits, spaces and symbols stay as they were.

Comparing with = and VLOOKUP in Excel ignore case, so UPPER is mainly for a consistent look: codes and abbreviations are usually written in capitals.

Common mistakes

  • UPPER doesn't fix look-alike characters. The letter O and the digit 0 look similar in a code, but for Excel they are different characters.
  • Extra spaces stay. If you need both, wrap the result in TRIM.
