Suppose in a cell sometime text looks like
;ABCD;EFGH
;;ABCD;EFGH;
How to remove semicolon only from beginning and end. The outcome should be
ABCD;EFGH
I'm sure there's a better way to do this, but it works!
Public Function SplitSemiColon(s As String) As String
While Left(s, 1) = ";"
s = Mid(s, 2)
Wend
While Right(s, 1) = ";"
s = Left(s, Len(s) - 1)
Wend
SplitSemiColon = s
End Function
Place the code in a new module and use the function on the worksheet like this (for example):
=SplitSemiColon(A1)
If there are no spaces, another alternative can be to convert them to spaces, trim, and convert back:
=Substitute(Trim(Substitute(A1,";"," "))," ",";")
TRIM removes extra spaces, so the above would turn ;A;;;B; into A;B, but VBA Trim doesn't:
[A1] = Replace(Trim(Replace([A1],";"," "))," ",";") ' ";A;;;B;" into "A;;;B"
If there are any spaces, they can be replaced with a different character, but it gets too messy:
=Substitute(Substitute(Trim(Substitute(Substitute(A1," ","_"),";"," "))," ",";"),"_"," ")

I have a VBA formula-function to split a string and add space between each character. It works fines only for an Ascii string. But I want to do the same for the Tamil Language. Since it is Unicode, the result is not readable. It splits even the auxiliary characters, Upper dots, Prefix, Suffix auxilary characters which should not be separated in Tamil/Hindi/Kanada/Malayalam/All India Languages. So, how to write a function to split a Tamil Word into readable characters.
Function AddSpace(Str As String) As String
Dim i As Long
For i = 1 To Len(Str)
AddSpace = AddSpace & Mid(Str, i, 1) & " "
Next i
AddSpace = Trim(AddSpace)
End Function
Adding Space is not the important point of this question. Splitting the Unicode string into an array from any of those languages is the requirement.
For example, the word, "பார்த்து" should be separated as "பா ர் த் து", not as "ப ா ர ் த ் த ு". As you can see, the first two letters "பா" (ப + ா) are combined. If I try to manually put a space in between them, I can't do it in any word processor. If you want to test, please put it in Notepad and add space between each character. It won't allow you to separate as ("ப ா"). So "பார்த்து" should be separated as "பா ர் த் து". It is the correct separation in Tamil like languages. This is the one that I am struggling to achieve in VBA.
The Character Code table for Tamil is here.
Tamil/Hindi/many Indian languages have (1)Consonants, (2)Independent vowels, (3)Dependent vowel signs, (4)Two-part dependent vowel signs. Among these 4 types, the first two are each one separate lettter, no issues with them. but the last 2 are dependent, they should not be separated from its joint character. For example, the letter, பா (ப + ் ), it contains one independent (ப) and one dependent (ா) letter.
If this info is not enough, please comment what should I post more.
(Note: It is possible in C#.Net using the code from the MS link by #Codo)
You can assign a string to a Byte array so the following might work
Dim myBytes as Byte
myBytes = "Tamilstring"
which generates two bytes for each character. You could then create a second byte array twice the size of the first by using space$ to crate a suitable string and then use a for loop (step 4) to copy two bytes at a time from the first to the second array. Finally, assign the byte array back to a string.
The problem you have is you are looking for what Unicode calls an extended grapheme cluster.
For a Unicode compatible regex engine that is simply /\X/
Not sure how you do that in VBA.
Referring the link mentioned by #ScottCraner in comments on the question and Character code for Tamil.
Check the result in cell A2 and highlighted in yellow are Dependent vowel signs which are used in DepVow string

Try below algorithm. which will concat all the mark characters with letter characters.
redim letters(0)
For i=1 To Len(Str)
If ascW(Mid(Str,i,1)) >3005 And ascW(Mid(Str,i,1)) <3022 Then
letters(UBound(letters)-1) = letters(UBound(letters)-1)+Mid(Str,i,1)
Else REDIM PRESERVE
letters(UBound(letters) + 1)
letters(UBound(letters)-1) = Mid(Str,i,1)
End If
Next
MsgBox(join(letters, ", "))'return பா, ர், த், து,
I am using the current code
If Left(cell.Value, 1) = ")" Then
....
End If
But it still seems to apply to every cell, not just the cells ending with ")"
Any help would be great ( I am still a noob)
Use the Right() function
If we test Left() & Right() on the string Stack we get....
Left(String, 1) = S
Left(String, 2) = St
Right(String, 1) = k
Right(String, 2) = ck
Since you are interested in the last character you want the first character starting from the right, not the left. Therefore, you should use...
If Right(Cell, 1) = ")" Then
'Do Something
End If
I created a macro for removing all whitespace in a string, specifically an email address. However it only removes about 95% of the whitespace, and leaves a few.
My code:
Sub NoSpaces()
Dim w As Range
For Each w In Selection.Cells
w = Replace(w, " ", "")
Next
End Sub
Things I have tried to solve the issue include:
~ Confirmed the spaces are indeed spaces with the Code function, it is character 32 (space)
~ Used a substitute macro in conjuction with the replace macro
~ Have additional macro utilizing Trim function to remove leading and trailing whitespace
~ Made a separate macro to test for non-breaking spaces (character 160)
~ Used the Find and Replace feature to search and replace spaces with nothing. Confirmed working.
I only have one cell selected when I run the macro. It selects and goes through all the cells because of the Selection.Cells part of the code.
A few examples:
1 STAR MOVING # ATT.NET
322 TRUCKING#GMAIL.COM
ALEZZZZ#AOL. COM.
These just contain regular whitespace, but are skipped over.
Just use a regular expression:
'Add a reference to Microsoft VBScript Regular Expressions 5.5
Public Function RemoveWhiteSpace(target As String) As String
With New RegExp
.Pattern = "\s"
.MultiLine = True
.Global = True
RemoveWhiteSpace = .Replace(target, vbNullString)
End With
End Function
Call it like this:
Sub NoSpaces()
Dim w As Range
For Each w In Selection.Cells
w.Value = RemoveWhiteSpace(w.Value)
Next
End Sub
Try this:
Sub NoSpaces()
Selection.Replace " ", ""
End Sub
Use "Substitute"
Example...
=SUBSTITUTE(C1:C18," ","")
Because you assume that Selection.Cells includes all cells on the sheet.
Cells.Replace " ", ""
And to add to the excellent advice from all the great contributors, try the
TRIM or LTRIM, or RTRIM and you can read more about these functions here:
https://msdn.microsoft.com/en-us/library/office/gg278916.aspx
Now this does not remove embedded spaces (spaces in between the letters) but it will remove any leading and trailing spaces.
Hope this helps.
Space Problem with Excel
ok, the only way i see this two types of space is by converting their Ascii code value of which I do it here
now to explain this function i made, it will just filter the string character by character checking if its equal to the two types of space i mentioned. if not it will concatenate that character into the string which will be the final value after the loop. hope this helps. Thanks.
Function spaceremove(strs) As String
Dim str As String
Dim nstr As String
Dim sstr As String
Dim x As Integer
str = strs
For x = 1 To VBA.Len(str)
sstr = Left(Mid(str, x), 1)
If sstr = " " Or sstr = " " Then
Else
nstr = nstr & "" & sstr
End If
Next x
spaceremove = nstr

I copied a HTML table with data and pasted in excel but the cells were filled with unwanted space and all methods posted here didn't work so I debugged and I discovered that it wasn't actually space chars (ASCII 32) it was Non-breaking space) (ASCII 160) or HTML
So to make it work with that Non-breaking space char I did this:
Sub NoSpaces()
Dim w As Range
For Each w In Selection.Cells
w.Value = Replace(w.Value, " ", vbNullString)
w.Value = Replace(w.Value, Chr(160), vbNullString)
Next
End Sub
I have a difficult situation and so far no luck in finding a solution.
My VBA collects number figures like $80,000.50. and I'm trying to get VBA to remove the last period to make it look like $80,000.50 but without using right().
The problem is after the last period there are hidden spaces or characters which will be a whole lot of new issue to handle so I'm just looking for something like:
replace("$80,000.50.",".**.",".**")
Is this possible in VBA?
I cant leave a comment so....
what about InStrRev?
Private Sub this()
Dim this As String
this = "$80,000.50."
this = Left(this, InStrRev(this, ".") - 1)
Debug.Print ; this
End Sub
Mid + Find
You can use Mid and Find functions. Like so:
The Find will find the first dot . character. If all the values you are collecting are currency with 2 decimals, stored as text, this will work well.
The formula is: =MID(A2,1,FIND(".",A2)+2)
VBA solution
Function getStringToFirstOccurence(inputUser As String, FindWhat As String) As String
getStringToFirstOccurence = Mid(inputUser, 1, WorksheetFunction.Find(FindWhat, inputUser) + 2)
End Function
Other possible solutions, hints

Untrimmable Spaces – Excel Formula
Ultimately, you can implement Regular expressions into Excel UDF: VBScript’s Regular Expression Support
How about:
Sub dural()
Dim r As Range
For Each r In Selection
s = r.Text
l = Len(s)
For i = l To 1 Step -1
If Mid(s, i, 1) = "." Then
r.Value = Mid(s, 1, i - 1) & Mid(s, i + 1)
Exit For
End If
Next i
Next r
End Sub
This will remove the last period and leave all the other characters intact. Before:
and after:
EDIT#1:
This version does not require looping over the characters in the cell:
Sub qwerty()
Dim r As Range
For Each r In Selection
If InStr(r.Value, ".") > 0 Then r.Characters(InStrRev(r.Text, "."), 1).Delete
Next r
End Sub
Shortest Solution
Simply use the Val command. I assume this is meant to be a numerical figure anyway? Get rid of commas and the dollar sign, then convert to value, which will ignore the second point and any other trailing characters! Robustness not tested, but seems to work...
Dim myString as String
myString = "$80,000.50. junk characters "
' Remove commas and dollar signs, then convert to value.
Dim myVal as Double
myVal = Val(Replace(Replace(myString,"$",""),",",""))
' >> myVal = 80000.5
' If you're really set on getting a formatted string back, use Format:
myString = Format(myVal, "$000,000.00")
' >> myString = $80,000.50
From the Documentation,
The Val function stops reading the string at the first character it can't recognize as part of a number. Symbols and characters that are often considered parts of numeric values, such as dollar signs and commas, are not recognized.
This is why we must first remove the dollar sign, and why it ignores all the junk after the second dot, or for that matter anything non numerical at the end!
Working with Strings
Edit: I wrote this solution first but now think the above method is more comprehensive and shorter - left here for completeness.
Trim() removes whitespace at the end of a string. Then you could simply use Left() to get rid of the last point...
' String with trailing spaces and a final dot
Dim myString as String
myString = "$80,000.50. "
' Get rid of whitespace at end
myString = Trim(myString)
' Might as well check if there is a final dot before removing it
If Right(myString, 1) = "." Then
myString = Left(myString, Len(myString) - 1)
End If
' >> myString = "$80,000.50"
I've written simple code in VBA (and seen questions here and here and none of these solutions work).
Dim toString As String
toString = cell.Value & "_"
If (InStr(toString, ",")) Then
toString = Replace(toString, ",", ".")
toString = Trim(toString)
cell.Value = " " + Left(toString, (Len(toString) - 1))
End If
Unfortunately, instead of string with dot separator, excel gives me double with comma in cell.Value. What curious is, when I exchange this whitespace with "_", it converts f. ex. 12,3 into _12.3. How can I fix it?
P.S. I add "_" at the end to ensure that toString will remain String.
I've had this issue before. You need to change the formatting of the cell before you write to it.
Application.Workbooks("Book1").Sheets("Sheet1").Range("A1:A100").NumberFormat = "#"
After that line runs you can simply write to the column like this:
Cells(1,1).Value = "12.3"
Excel will keep the string formatting and not convert it to a double.
Hope this helps.
