It is a simple code I got from running a macro but it takes a long time to process. Can anyone who's good at vba fix this please? Thanks.
Sub ClearAll()
    Application.ScreenUpdating = False
    Range("H2:H11").Select
    Selection.ClearContents
    Range("A2:A100").Select
    Selection.ClearContents
    Selection.ClearFormats
    Sheets(2).Select
    Cells.Select
    Selection.ClearContents
    ThisWorkbook.Sheets(3).Rows("2:" & Rows.Count).Delete
    Sheets(1).Select
    Range("A2").Select
    ActiveSheet.UsedRange
    ThisWorkbook.Save
    Application.ScreenUpdating = True
End Sub
