Dear experts,

Could any one please provide me a vba query which can extract the unique values in a column.

The vba will be in the file on which the query has to be run.

the vba should be enable for prompting for selection of sheet and column.

Thank you

Try this:
Sub test()
  'Dim wsList() As Strings
  Dim i As Long
  Dim wsname As String
  Dim col As String
  Dim ncol As Integer
 
  Dim c As Range
  Dim R As Range
  Dim result As String
 
 
  wsname = InputBox("Please enter the sheet name", "Sheet Name")
  col = InputBox("Please enter the Column name or number", "Column Name")
 
  If IsNumeric(col) Then
    Set R = Sheets(wsname).Columns(CInt(col))
  Else
    Set R = Sheets(wsname).Columns(col)
  End If
 
  i = R.Rows(R.Rows.Count).End(xlUp).Row
 
  For Each c In Range(R.Rows(1), R.Rows(i))
    If WorksheetFunction.CountIfs(R, "=" & c.Value) = 1 Then
        result = result & c.Value & vbCrLf
    End If
  Next c
  MsgBox result
End Sub
