View Full Version : Counting repetitions of string of words to counting group of words in one cell

Hello!

I need some help to update an existing code, and make it more efficient for my work.

The code below is not from me, but I don't remember the person who created it (all thanks to them still).

This code regroup the most repeated string of words in a text and count the most repeated.The regroupments are between 1 and 5 words.

But instead of the most repeated string of words (next to each other), I would like the most repeated group of words in one cell, no matter the example. For example, if ''pencil office problem'' are in the same cell 430 times, I want the macro to identify them.

I think it's possible to do it from the code I already have, and I want to keep the format in which they are presented: but I'm a total newbie in VBA, and so I need experts on this to help me figure it out!

Here is the code:


Option Explicit

Sub PHRASES_TEST_1()
'1. Add reference to "Microsoft VBScript Regular Expressions 5.5" (you need to do it once only):
' In Visual Basic Editor menu, select Tools –> References, then select Microsoft VBScript Regular Expressions 5.5, then click OK.
'2. Data must be in column A, start at A1
'3. Run Word_Phrase_Frequency_v1

'--- CHANGE sNumber & xPattern VALUE TO SUIT -----------------------------------
Dim lastRow As Long
Dim myRange As Range
' Find lastRow in column A
lastRow = Cells(Rows.Count, "A").End(xlUp).Row

' Set range to look at
Set myRange = Range("A4:A" & lastRow)
Const sNumber As String = "1,2,3,4,5" '"1,2,3"
'sNumber = "1" will generate 1 word frequency list
'sNumber = "1,2,3" will generate 1 word, 2 word & 3 word frequency list
Const xPattern As String = "A-Z0-9_'"
'define the word characters, the above pattern will include letter, number, underscore & apostrophe as word character
'word with apostrophe such as "you're" counts as one word.
'word with underscore such as "aa_bb" counts as one word.
Const xCol As String = "C:ZZ" 'columns to clear
Dim i As Long, j As Long
Dim txa As String
Dim z, t
t = Timer
Application.ScreenUpdating = False
Range(xCol).Clear
'if there are errors, remove them
On Error Resume Next
Range("A:A").SpecialCells(xlCellTypeFormulas, xlErrors).ClearContents
Range("A:A").SpecialCells(xlConstants, xlErrors).ClearContents
On Error GoTo 0
j = Range("A" & Rows.Count).End(xlUp).Row
If j < 65000 Then
txa = Join(Application.Transpose(Range("A1", Cells(Rows.Count, "A").End(xlUp))), "")
Else
For i = 1 To j Step 65000
txa = txa & Join(Application.Transpose(Range("A" & i).Resize(65000)), "") & ""
Next
End If
z = Split(sNumber, ",")
'TO PROCESS
For i = LBound(z) To UBound(z)
Call toProcessY(CLng(z(i)), txa, xPattern)
Next
Range(xCol).Columns.AutoFit
Application.ScreenUpdating = True
Debug.Print "It's done in: " & Timer - t & " seconds"
End Sub

Sub toProcessY(n As Long, ByVal tx As String, xP As String)
'phrase frequency
Dim regEx As Object, matches As Object, x As Object, d As Object
Dim i As Long, rc As Long
Dim va, q
Set regEx = CreateObject("VBScript.RegExp")
With regEx
.Global = True
.MultiLine = True
.IgnoreCase = True
End With
If n > 1 Then
regEx.Pattern = "( ){2,}"
If regEx.Test(tx) Then
tx = regEx.Replace(tx, "") 'remove excessive space
End If
tx = Trim(tx)
' regEx.Pattern = "[^A-Z0-9_' ]+"
regEx.Pattern = "[^" & xP & " ]+" 'exclude xp and space
If regEx.Test(tx) Then
tx = regEx.Replace(tx, vbLf) 'replace non words character (excluding space) with new line char (vbLf)
End If
tx = Replace(tx, vbLf & "", vbLf & "") 'remove space in the beginning of every line
End If
Set d = CreateObject("scripting.dictionary")
d.CompareMode = vbTextCompare
' regEx.Pattern = Trim(WorksheetFunction.Rept("[A-Z0-9_']+ ", n)) 'match n words (the phrase) separated by a space
regEx.Pattern = Trim(WorksheetFunction.Rept("[" & xP & "]+ ", n)) 'match n words (the phrase) separated by a space
Set matches = regEx.Execute(tx)
For Each x In matches
d(CStr(x)) = d(CStr(x)) + 1 'get phrase frequency
Next
For i = 1 To n - 1
regEx.Pattern = "^[" & xP & "]+ "
If regEx.Test(tx) Then
tx = regEx.Replace(tx, "") 'remove first word in each line to get different combination of n words (phrase)
' regEx.Pattern = Trim(WorksheetFunction.Rept("[A-Z0-9_']+ ", n))
regEx.Pattern = Trim(WorksheetFunction.Rept("[" & xP & "]+ ", n))
Set matches = regEx.Execute(tx)
For Each x In matches
d(CStr(x)) = d(CStr(x)) + 1 'get phrase frequency
Next
End If
Next
If d.Count = 0 Then MsgBox "Nothing with " & n & " word phrase found": Exit Sub
rc = Cells(1, Columns.Count).End(xlToLeft).Column
'put the result
With Cells(2, rc + 2).Resize(d.Count, 2)
Select Case d.Count
Case Is < 65536 'Transpose function has a limit of 65536 item to process
.Value = Application.Transpose(Array(d.Keys, d.Items))
Case Is <= 1048500
ReDim va(1 To d.Count, 1 To 2)
i = 0
For Each q In d.Keys
i = i + 1
va(i, 1) = q: va(i, 2) = d(q)
Next
.Value = va
Case Else
MsgBox "Process is canceled, the result is more than 1048500 rows"
End Select
.Sort Key1:=.Cells(1, 2), Order1:=xlDescending, Key2:=.Cells(1, 1), Order2:=xlAscending, Header:=xlNo
End With
Cells(1, rc + 2) = n & " WORD"
Cells(1, rc + 3) = "COUNT"
End Sub

And I attached an example of what it looks like when it's run.

Thank you all for your help!

Perhaps you could edit it as below to work with a single cell, in the below instance cell A1:

Sub PHRASES_TEST_1()
Dim myRange As Range
Dim i As Long, j As Long
Dim txa As String
Dim z, t

' Set range to look at
Set myRange = Range("A1") ' set to the range that has all of the text in one cell
Const sNumber As String = "1,2,3,4,5" '"1,2,3"
Const xPattern As String = "A-Z0-9_'"
Const xCol As String = "C:ZZ" 'columns to clear

t = Timer
Application.ScreenUpdating = False
Range(xCol).Clear
txa = myRange.Value
z = Split(sNumber, ",")


For i = LBound(z) To UBound(z)
Call toProcessY(CLng(z(i)), txa, xPattern)
Next
Range(xCol).Columns.AutoFit
Application.ScreenUpdating = True
Debug.Print "It's done in: " & Timer - t & " seconds"
End Sub


Sub toProcessY(n As Long, ByVal tx As String, xP As String)
Dim regEx As Object, matches As Object, x As Object, d As Object
Dim i As Long, rc As Long
Dim va, q

Set regEx = CreateObject("VBScript.RegExp")
With regEx
.Global = True
.MultiLine = True
.IgnoreCase = True
End With
If n > 1 Then
regEx.Pattern = "( ){2,}"
If regEx.Test(tx) Then
tx = regEx.Replace(tx, "") 'remove excessive space
End If
tx = Trim(tx)
' regEx.Pattern = "[^A-Z0-9_' ]+"
regEx.Pattern = "[^" & xP & " ]+" 'exclude xp and space
If regEx.Test(tx) Then
tx = regEx.Replace(tx, "") 'replace non words character (excluding space) with vbnullstring
End If
tx = Replace(tx, vbLf & "", vbLf & "") 'remove space in the beginning of every line
End If

Set d = CreateObject("scripting.dictionary")
d.CompareMode = vbTextCompare
regEx.Pattern = Trim(WorksheetFunction.Rept("[" & xP & "]+ ", n)) 'match n words (the phrase) separated by a space
Set matches = regEx.Execute(tx)
For Each x In matches
d(CStr(x)) = d(CStr(x)) + 1 'get phrase frequency
Next
For i = 1 To n - 1
regEx.Pattern = "^[" & xP & "]+ "
If regEx.Test(tx) Then
tx = regEx.Replace(tx, "") 'remove first word in each line to get different combination of n words (phrase)
regEx.Pattern = Trim(WorksheetFunction.Rept("[" & xP & "]+ ", n))
Set matches = regEx.Execute(tx)
For Each x In matches
d(CStr(x)) = d(CStr(x)) + 1 'get phrase frequency
Next
End If
Next

If d.Count = 0 Then MsgBox "Nothing with " & n & " word phrase found": Exit Sub
rc = Cells(1, Columns.Count).End(xlToLeft).Column
With Cells(2, rc + 2).Resize(d.Count, 2)
Select Case d.Count
Case Is < 65536 'Transpose function has a limit of 65536 item to process
.Value = Application.Transpose(Array(d.Keys, d.Items))

Case Is <= 1048500
ReDim va(1 To d.Count, 1 To 2)
i = 0
For Each q In d.Keys
i = i + 1
va(i, 1) = q: va(i, 2) = d(q)
Next
.Value = va

Case Else
MsgBox "Process is canceled, the result is more than 1048500 rows"
End Select
.Sort Key1:=.Cells(1, 2), Order1:=xlDescending, Key2:=.Cells(1, 1), Order2:=xlAscending, Header:=xlNo
End With

Cells(1, rc + 2) = n & " WORD"
Cells(1, rc + 3) = "COUNT"
End Sub
