PROPER function

PROPER capitalizes the first letter of each word and lowercases the rest. It cleans up names, cities and titles typed in all caps or all lowercase, though it needs help with names like McDonald and small words like "of".

Common mistakes

What you seeWhy, and how to fix it
Mc and Mac namesPROPER turns MCDONALD into Mcdonald. Fix exceptions afterward with SUBSTITUTE, or by hand.
Small words capitalized"head of sales" becomes "Head Of Sales". Lowercase them again with SUBSTITUTE: =SUBSTITUTE(PROPER(A2)," Of "," of ").
Acronyms lose their capitalsPROPER turns "IBM partner" into "Ibm Partner". Keep acronyms in their own column or restore them with SUBSTITUTE.

Tips

  • Clean spacing and case in one step with =PROPER(TRIM(A2)).
  • PROPER also capitalizes after an apostrophe or hyphen, so o'brien-smith becomes O'Brien-Smith.

Questions

How do I capitalize the first letter of each word in Excel?

Use =PROPER(A2). It capitalizes every word and lowercases the rest of each word.

How do I capitalize only the first letter of a sentence?

Combine UPPER, LOWER, LEFT and MID: =UPPER(LEFT(A2,1))&LOWER(MID(A2,2,999)).
