The LOWER, UPPER, and PROPER functions in Excel are powerful tools for text manipulation. They help format text data by converting text to lowercase, uppercase, or proper case. This article will provide syntax, examples, exercises, and solutions to help you understand these functions.
Syntax
| Function | Description | Syntax |
|---|---|---|
| LOWER | Converts all uppercase letters in a text string to lowercase. | LOWER(text) |
| UPPER | Converts all lowercase letters in a text string to uppercase. | UPPER(text) |
| PROPER | Capitalizes the first letter of each word in a text string. | PROPER(text) |
Each function takes a single argument, text, which is the text string you want to convert. The result is a new text string in the desired case format.
