Change case of text with Excel Functions

Excel provides three essential functions to modify text case directly in your worksheets:

LOWER: Converts all text to lowercase (e.g., "EXCEL" becomes "excel").

UPPER: Transforms all text to uppercase (e.g., "excel" becomes "EXCEL").

PROPER: Capitalizes the first letter of each word and sets all others to lowercase (e.g., "i am jay" becomes "I Am Jay").

Suppose you have text that needs case conversion. For example, to change text to lowercase:

To change all the text case to lower case, please do as follows:

1. In an adjacent blank cell, such as cell C1, type the formula below, press the Enter key.

=LOWER(A1)

2. Select cell C1 and drag the fill handle to apply this formula to other cells as needed. The text will convert to lowercase as you extend the formula.

3. Since these are formulas, remember to paste them as values if copying to another location.

Notes:
  • To change all the text case to upper case, please enter this formula below.
  • = UPPER(A1)
  • To change all the text case to proper case, please enter this formula below.
  • =PROPER(A1)
