Find and Format All Formulas in a Workbook

This simple macro can help find and format all cells that contain formulas.

VBA Code

Sub FormatFormulas()
'Step 1:  Declare your Variables
    Dim ws As Worksheet
'Step 2: Avoid Error if no formulas are found
    On Error Resume Next
'Step 3:  Start looping through worksheets
    For Each ws In ActiveWorkbook.Worksheets
'Step 4:  Find cells and highlight them
    With ws.Cells.SpecialCells(xlCellTypeFormulas)
    .Interior.ColorIndex = 36
    End With
'Step 5: Get next worksheet
    Next ws
End Sub

How This Macro Works

Excel has a set of predefined "special cells" that you can select by using the Go To Special dialog box. To select special cells manually, go to the Home tab on the Ribbon and select Go To Special. This brings up the Go To Special dialog box shown in Figure below. Here, you can select a set of cells based on a few defining attributes. One of those defining attributes is formulas. Selecting the Formulas option effectively selects all cells that contain formulas.
Go To Special

This macro programmatically does the same thing for the entire workbook at the same time. Here, we are using the SpecialCells method of the Cells collection. The SpecialCells method requires type parameter that represents the type of special cell. In this case, we are using xlCellTypeFormulas.

In short, we are referring to a special range that consists only of cells that contain formulas. We refer to this special range using the With…End With statement. This statement tells Excel that any action you perform applies only to the range to which you’ve pointed. Here, we are coloring the interior of the cells in the chosen range.

  1. Step 1 declares an object called ws. This creates a memory container for each worksheet the macro loops through.
  2. If the spreadsheet contains no formulas, Excel throws an error. To avoid the error, we tell Excel to continue with the macro if an error is triggered.
  3. Step 3 begins the looping, telling Excel to evaluate all worksheets in the active workbook.
  4. In this Step, the macro selects all cells containing formulas, and then formats them.
  5. In Step 5, we loop back to get the next sheet. After all of the sheets are evaluated, the macro ends.
