This udf extracts all words containing a specified string.


Cell range B1:M50 contains random sentences. I have inserted some random emails in this range.

VBA code

Function FilterWords(rng As Range, str As String) As Variant()
Dim x As Variant, Wrds() As Variant, Cells_row As Long
Dim Cells_col As Long, Words As Long, y() As Variant

ReDim y(0)
Wrds = rng.Value

For Cells_row = LBound(Wrds, 1) To UBound(Wrds, 1)
  For Cells_col = LBound(Wrds, 2) To UBound(Wrds, 2)
    x = Split(Wrds(Cells_row, Cells_col))
      For Words = LBound(x) To UBound(x)
        If InStr(x(Words), str) Then
          y(UBound(y)) = x(Words)
          ReDim Preserve y(UBound(y) + 1)
        End If
      Next Words
  Next Cells_col
Next Cells_row

ReDim Preserve y(UBound(y) - 1)
FilterWords = Application.Transpose(y)
End Function

Where to do I copy the code?

  2. Click Module on the Insert menu
  3. Copy and paste the user defined function into module
  4. Exit visual basic editor
