Best Practices

  • Any character that is not a letter (like a space, hyphen, or number) acts as a word separator, causing the next letter to be capitalized.
  • PROPER is useful for formatting names before sending automated emails.

Common Mistakes

  • PROPER will lowercase abbreviations (e.g. "USA" becomes "Usa" and "CEO" becomes "Ceo").
