Insert a function to delete any words with less than 3 characters in a VBA code
Hello,
I'm a VBA newbie, so please with me while I try to explain my problem.
I'm a marketing analyst, and found recently a VBA code online that helps me greatly in my work. This code regroup the most repeated string of words in a text and count the most repeated (I unfortunately forgot who did this amazing code, but I'm grateful for them).
It works well, but I want to tweak it a little: I would like to delete all words with less than 3 characters before the function is run, for it to regroup only words with more than 4 characters. I want it to be included in my existing code, for it to run in one macro only: I want to share this VBA with my colleagues and, since they are not excel tech-savy, running one macro will simplify . I tried to add existing functions that do the trick to my existing code, but unfortunately I always run with errors, and I'm not good enough to change it.
So, here is my original code, that regroups all repetitive string of words:
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
If you need a base to add the function to delete 3 words under, here is a function I used first and put at the beginning of this code, where it selected specific words to delete before regrouping: and it worked wonderfully!
Code:
' Replace pas
myRange.Replace What:=" pas ", Replacement:=" ", LookAt:=xlPart, _
SearchOrder:=xlByRows, MatchCase:=False, SearchFormat:=False, _
ReplaceFormat:=False
A full example is attached.
Thank you for your help!
