How to highlight active row and column in Excel

This tutorial explores three methods for dynamically highlighting the selected cell's row and column in Excel, enhancing worksheet navigation. Let's examine each approach:

Method 1: VBA for Dynamic Highlighting

This method uses VBA's SelectionChange event to programmatically highlight the active cell's row and column. The code first clears all cell background colors and then applies highlighting to the selected cell's row and column using specified ColorIndex values.

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    If Target.Cells.Count > 1 Then Exit Sub
    Application.ScreenUpdating = False
    Cells.Interior.ColorIndex = 0
    With Target
        .EntireRow.Interior.ColorIndex = 38
        .EntireColumn.Interior.ColorIndex = 24
    End With
    Application.ScreenUpdating = True
End Sub

Customization options include altering the ColorIndex values for different highlight colors or highlighting only the row or column. The code must be added to the worksheet's VBA module (not a standard module). Saving the file as a Macro-Enabled Workbook (.xlsm) is crucial.

Advantages: Backend operation, no user adjustments needed, compatibility across Excel versions.

Disadvantages: Clears all existing cell background colors, disables undo functionality (Ctrl Z).

Method 2: Conditional Formatting (with VBA Enhancement)

This method leverages Excel's conditional formatting with formulas referencing the CELL function. The formulas dynamically highlight the active row and/or column based on the selected cell's coordinates.

• Highlight Active Row: =CELL("row")=ROW()
• Highlight Active Column: =CELL("col")=COLUMN()
• Highlight Active Row and Column: =OR(CELL("row")=ROW(), CELL("col")=COLUMN())

Because Excel doesn't automatically recalculate on selection changes, manual recalculation (F9) or the following VBA code in the worksheet module is needed:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    Target.Calculate
End Sub

Advantages: Preserves existing cell formatting.

Disadvantages: May impact performance on large workbooks due to recalculations, requires Excel 2007 or later.

Method 3: Conditional Formatting and VBA (Optimized)

This approach optimizes performance by using a "helper sheet" to store the active row and column numbers, which are then referenced in the conditional formatting formulas.

1. Create a "Helper Sheet."
2. Add this VBA code to the target worksheet's module:

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
    Application.ScreenUpdating = False
    Worksheets("Helper Sheet").Cells(2, 1) = Target.Row
    Worksheets("Helper Sheet").Cells(2, 2) = Target.Column
    Application.ScreenUpdating = True
End Sub

3. Use these conditional formatting formulas:

• Highlight Active Row: =ROW()='Helper Sheet'!$A$2
• Highlight Active Column: =COLUMN()='Helper Sheet'!$B$2
• Highlight Active Row and Column: =OR(ROW()='Helper Sheet'!$A$2, COLUMN()='Helper Sheet'!$B$2)

Advantages: Optimized performance, works in all Excel versions.

Disadvantages: More complex setup.
