If you need to identify all characters in cells are lowercase, you can use a formula based on the LOWER function and the EXACT function. Like this:
=EXACT(B1,LOWER(B1))
Type this formula into cell C1, and press Enter key to apply this formula. If all letters are lowercases, and it returns TRUE. Otherwise, it returns FALSE. Then drag the AutoFill Handle down to other cells to apply this formula.
