These formulas and the ones in the download are from Krishnakumar a OzMVP on our help forum.
=LOOKUP(REPT("z",255),A:A)
=LOOKUP(9.99999999999E+307,B:B)
=INDEX(C:C,MAX(MATCH("zzzzzzzzzz",C:C),MATCH(9.9999E+307,C:C)))

The code below Loops through all Worksheets in the active Workbook and clears cells with the Style name specified by the user. It uses an InputBox to collect the Style name. It also incorporates a Select Case Statement to exclude/include specified Sheets by CodeName. It also uses the UserInterFaceOnly argument of the Sheet Protection Method, so while code can run on protected sheets, normal users cannot change locked cells.
The other important element is the use of the SpecialCells Method to ensure only the cell the user wants (Formulae/Constants or both) are affected. This is asked of the user via the MsgBox Function.
The code is optimized for both speed and efficiency, which should not be confused with the shorter the code the faster and more efficient it is.
Naturally the code uses Styles only as an example, it could any code that uses cell Properties, Objects and Methods.
Sub ClearCellsWithStyleX()
Dim strStyleName As String
Dim lClearFormulae As Long
Dim wsheet As Worksheet
Dim rCcells As Range, rFcells As Range

strStyleName = InputBox("Type the style name", _
"CLEAR CELL WITH STYLE...", ThisWorkbook.Styles(1))
If strStyleName = vbNullString Then Exit Sub 'Cancelled
'Find out if formulae should be cleared
lClearFormulae = MsgBox("Clear formulae cells with the Style " _

'Loop through all Worksheets
For Each wsheet In Worksheets
