Sort alphabets in a word/string - excel

Question

Does excel vba have a function to sort a given word or string alphabetically? Also, what is this kind of a string manipulation called in technical/programming terms?
For e.g. Word = "Somestring"
Output = "egimnorSst"
Thanks.

Answer 1

If you have Excel O365 with the functions I've used below, you can use this formula:
=TEXTJOIN(,,SORT(MID(A1,SEQUENCE(LEN(A1)),1)))
or as indicated by #JvdV, instead of TEXTJOIN we can use the simpler:
=CONCAT(SORT(MID(A1,SEQUENCE(LEN(A1)),1)))
If y0u don't have those functions, you would need a UDF written in VBA.
Here is one that, since the sort strings should be relatively short, uses a simple Bubblesort to sort the string elements.
Option Explicit
Option Compare Text
Function sortString(S As String) As String
Dim str() As String
Dim I As Long
ReDim str(1 To Len(S))
For I = 1 To Len(S)
str(I) = Mid(S, I, 1)
Next I
BubbleSort str
sortString = Join(str, "")
End Function
Sub BubbleSort(TempArray)
'copied directly from support.microsoft.com
Dim temp As Variant
Dim I As Integer
Dim NoExchanges As Integer
' Loop until no more "exchanges" are made.
Do
NoExchanges = True
' Loop through each element in the array.
For I = LBound(TempArray) To UBound(TempArray) - 1
' If the element is greater than the element
' following it, exchange the two elements.
If TempArray(I) > TempArray(I + 1) Then
NoExchanges = False
temp = TempArray(I)
TempArray(I) = TempArray(I + 1)
TempArray(I + 1) = temp
End If
Next I
Loop While Not (NoExchanges)
End Sub

Though the question itself is very minimal I would like to answer nonetheless. If you not bothered having S and s reversed than:
Sub Test()
Dim x As Long
Dim str As String: str = "Somestring"
With CreateObject("System.Collections.ArrayList")
For x = 1 To Len(str)
.Add Mid(str, x, 1)
.Sort
Next
Debug.Print Join(.Toarray, "")
End With
End Sub
Results in:
egimnorsSt
If that is not what you want it becomes a bit more complicated I think since we cannot use ASCII codes (S = 83 and way lower than the other characters).
It may not be super pretty but try:
Sub Test()
Dim x As Long
Dim str As String, str_new As String
str = "abcdABCD"
With CreateObject("System.Collections.ArrayList")
For x = 1 To Len(str)
.Add Mid(str, x, 1)
.Sort
Next
str_new = Join(.Toarray, "")
End With
With CreateObject("vbscript.regexp")
.Global = True
.IgnoreCase = True
.Pattern = "([a-z])\1+"
If .Test(str_new) Then
For Each Match In .Execute(str_new)
str_new = Replace(str_new, Match, Application.Proper(Match)) 'Assuming no more than 1 of the same uppercase letters.
Next
End If
End With
Debug.Print str_new
End Sub
Results in:
AaBbCcDd
Another option if you have ExcelO365 with new DA-functions and value in A1:
=CONCAT(SORT(MID(A1,ROW(A1:INDEX(A:A,LEN(A1))),1)))
This would actually return egimnorSst
