How to Handle Missing or Empty Cells in Excel Using VBA?

[Nouramishaal]

Hello,

I’m working with an Excel dataset that contains missing values (empty cells), and I’m unable to retrieve the original data for those cells. I would like to know the best way to handle these empty cells using VBA.

Specifically:

- I want to identify and process these cells.​

- Depending on best practices, I might either:​

1. Fill them with a default value (like `"N/A"` or `0`), or
2. Delete the entire column if it has missing critical data.

Could someone please guide me on how to approach this using VBA?
Sample VBA code or suggestions on handling missing data effectively would be greatly appreciated.


Thank you in advance!

Best regards,
Noura

Option 1: Fill All Empty Cells with a Default Value

>>> use code - tags <<<

Sub FillEmptyCells()
    Dim ws As Worksheet
    Dim dataRange As Range
    Dim cell As Range
    Dim defaultValue As Variant
   
    Set ws = ThisWorkbook.Sheets("Sheet1")
    defaultValue = "N/A" ' Change to 0 or "" if needed

    ' Define the used range of your data (excluding empty rows/columns outside your data)
    Set dataRange = ws.UsedRange

    ' Loop through each cell and fill blanks
    For Each cell In dataRange
        If IsEmpty(cell.Value) Then
            cell.Value = defaultValue
        End If
    Next cell

    MsgBox "Empty cells filled with '" & defaultValue & "'"
End Sub

Option 2: Delete Columns That Contain Missing Data

Sub DeleteColumnsWithMissingData()
    Dim ws As Worksheet
    Dim lastCol As Long, lastRow As Long
    Dim col As Long
    Dim rngCol As Range

    Set ws = ThisWorkbook.Sheets("Sheet1")
    lastRow = ws.Cells(ws.Rows.Count, 1).End(xlUp).Row
    lastCol = ws.Cells(1, ws.Columns.Count).End(xlToLeft).Column

    Application.ScreenUpdating = False

    ' Loop backwards so column indexes don't shift after deletion
    For col = lastCol To 1 Step -1
        Set rngCol = ws.Range(ws.Cells(2, col), ws.Cells(lastRow, col)) ' Exclude header (row 1)
        If Application.WorksheetFunction.CountBlank(rngCol) > 0 Then
            ws.Columns(col).Delete
        End If
    Next col

    Application.ScreenUpdating = True
    MsgBox "Columns with missing data have been deleted."
End Sub
