Trace Dependents:
Displays the relationships between formulas and cells. To execute Trace Dependents selection must point to a cell or range having formula.
- Select the cell for which you want to identify the dependent cells.
- To display a tracer arrow to each cell that is dependent on the active cell, on the Formulas tab, in the Formula Auditing group, click Trace Dependents .

In Above example I have used total three formulas to identify where A and B formulas are dependent on Formula A-B. Let’s put some code around to achieve above manual process to make it automated 🙂
Note: in this example the C# code style is used with VSTO (Visual Studio Tools for Office) technology which is a Office development solution and you should have following prerequisites before using given code:
Prerequisites:
- Visual Studio 2015 or above having Microsoft Office for Developer Tool installed
- Create Excel Addin in C# code style (Visual Studio Tools for Office)
- Create a ribbon designer and put button
C# code example:
private void btnTraceDependets_Click(object sender, RibbonControlEventArgs e) { //Get current selection excel.Range oRange = Globals.ThisAddIn.Application.Selection; //check if selection has formula because trace Dependents works only on formula cells if (Globals.ThisAddIn.Application.WorksheetFunction.IsFormula(oRange)) { oRange.ShowDependents(); } }
VB.Net code example:
Private ShowDepndents_Click(sender As Object, e As RibbonControlEventArgs) Handles ShowDepndents.Click 'Bind Range object from selection Dim oRange As excel.Range oRange=Globals.ThisAddIn.Application.Selection 'check if selection has formula because trace Dependents works only on formula cells if Globals.ThisAddIn.Application.WorksheetFunction.IsFormula(oRange) Then oRange.ShowDependents() End If End Sub
VBA code example:
Public Sub ShowDependents() 'Bind range object Dim oRange As Range Set oRange = Selection 'Check if selction points to non formula range If WorksheetFunction.IsFormula(oRange) Then oRange.ShowDependents End If End Sub
