I am trying to identify common themes from free-form text extracted from a case management system. I found a VBA macro that analyzes free-form text and counts the frequency of each word. However, the requirement is analyze free-form text and count the frequency of common phrases.

Anyone know of a VBA macro or built-in function that can do this? Or, can I modify the VBA macro below to do what I'm looking for?

Sub MakeWordList()
Dim InputSheet As Worksheet
Dim WordListSheet As Worksheet
Dim PuncChars As Variant, x As Variant
Dim i As Long, r As Long
Dim txt As String
Dim wordCnt As Long
Dim AllWords As Range
Dim PC As PivotCache
Dim PT As PivotTable

Application.ScreenUpdating = False
Set InputSheet = ActiveSheet
Set WordListSheet = Worksheets.Add(after:=Worksheets(Sheets.Count))
WordListSheet.Range("A1") = "All Words"
WordListSheet.Range("A1").Font.Bold = True
InputSheet.Activate
wordCnt = 2
PuncChars = Array(".", ",", ";", ":", "'", "!", "#", _
"$", "%", "&", "(", ")", " - ", "_", "--", "+", _
"=", "~", "/", "\", "{", "}", "[", "]", """", "?", "*")
r = 1

' Loop until blank cell is encountered
Do While Cells(r, 1) <> ""
' covert to UPPERCASE
txt = UCase(Cells(r, 1))
' Remove punctuation
For i = 0 To UBound(PuncChars)
txt = Replace(txt, PuncChars(i), "")
Next i
' Remove excess spaces
txt = WorksheetFunction.Trim(txt)
' Extract the words
x = Split(txt)
For i = 0 To UBound(x)
WordListSheet.Cells(wordCnt, 1) = x(i)
wordCnt = wordCnt + 1
Next i
r = r + 1
Loop

' Create pivot table
WordListSheet.Activate
Set AllWords = Range("A1").CurrentRegion
Set PC = ActiveWorkbook.PivotCaches.Add _
(SourceType:=xlDatabase, _
SourceData:=AllWords)
Set PT = PC.CreatePivotTable _
(TableDestination:=Range("C1"), _
TableName:="PivotTable1")
With PT
.AddDataField .PivotFields("All Words")
.PivotFields("All Words").Orientation = xlRowField
End With
End Sub
