Usage Notes

PROPER will capitalize the first letter in a text string and any other letter following a non-letter character. Numbers and punctuation are not affected.

Letters that are already capitalized may be affected. For example =PROPER(reno, NV) would return Reno, Nv. While the "R" is correctly capitalized, the "v" is converted from upper to lowercase.
