You probably already know that you can select all the cells containing formulas in a worksheet by pressing F5 and choosing Special | Formulas. If you need to keep a constant eye on where formulas are located, then repeatedly doing the selecting can get tedious. A better solution is to use the conditional formatting capabilities of Excel to highlight cells with formulas.
Before you can use conditional formatting, however, you need to create a user-defined function that will return True or False, depending on whether there is a formula in a cell. The following macro will do the task very nicely:
Function HasFormula(rCell As Range) As Boolean Application.Volatile HasFormula = rCell.HasFormula End Function
To use this with conditional formatting, select the cells you want checked, and then follow these steps:

Microsoft introduced the ISFORMULA function with Excel 2013. The ISFORMULA function allows you to highlight cells that contain formulas without using a macro. To use this function with conditional formatting, select the cells you want checked, and then follow these steps:

You might be interested in the freely available FormulaCellsCF macro in My Excel Toolbox. Here is a simplfied version:
Public Sub FormulaCellsCF()
Const F = "=ISFORMULA(A1)+N(""FormulaCellsCF"")"
For Each FC In ActiveSheet.Cells.FormatConditions
    If FC.Type = xlExpression And FC.Formula1 = F Then
        FC.Delete
        Done = True
    End If
Next FC
If Done Then Exit Sub
With ActiveSheet.Cells.FormatConditions.Add(xlExpression, , F)
    .Interior.Color = &HE6E6E6
End With
End Sub
