Always apply UPPER in a new column to preserve your original data.

Non-Text Cells

If a referenced cell contains a number or special character, the formula will return it unchanged.

Limitations of the UPPER Function

• Only affects alphabetic characters.
• Cannot apply sentence case or title case – use PROPER or LOWER for that.
• Formatting won’t change if the input is already in uppercase.
