Searching for a string of text within a longer string of text within an entire column

Here is a VBA solution.

Option Explicit
Option Compare Text

Sub FindText()
    Dim crit As String, s As String, x As String
    Dim i As Long, j As Long, lr As Long, lr2 As Long
    lr = Range("A" & Rows.Count).End(xlUp).Row
    lr2 = Range("C" & Rows.Count).End(xlUp).Row
    For j = 2 To lr2
        s = ""
        x = ""
        crit = Range("C" & j)
        For i = 2 To lr
            If InStr(Range("A" & i), crit) > 0 Then
                Range("D" & j) = "Found"
                x = Range("A" & i).Address
                s = s & " ," & x
                Range("F" & j) = s
            End If
        Next i
    Next j
End Sub
