PROPER Function in Excel

Beginner

Converts the first letter of each word to uppercase and remaining letters to lowercase.

Syntax

=PROPER(text)

Example

Use Case

Format names properly: 'john smith' becomes 'John Smith'.

Common Errors to Avoid

  • Capitalizes after any non-letter character (including apostrophes: o'brien → O'Brien)
  • May incorrectly capitalize: 'mcDonald' → 'Mcdonald' (should be 'McDonald')
  • Numbers reset capitalization: 'abc123def' → 'Abc123Def'

Pro Tips

Great for standardizing name formatting. Be aware of edge cases like 'McDonald', 'O'Brien', or 'iPhone'. For business names with specific capitalization, use manual entry or find-replace. Always review results for proper nouns.
