Adding a space between two words once - excel

Question

I completed code to remove any data in front of a string, add some text (with a space) to the front and store it back in the cell.
However, every time I run the macro (to check if changes that I've made are working for example), a new space is added in between the words.
The code that removes anything before the name and adds the required string. I have called a InStr function and stored the value in integer pos. Note that this is in a loop over a specific range.
If pos > 0 Then
'Removes anything before the channel name
cellValue.Offset(0, 2) = Right(cell, Len(cell) - InStr(cell, pos) - 2)
'Add "DA" to the front of the channel name
cellValue.Offset(0, 0) = "DA " & Right(cell, Len(cell) - InStr(cell, pos) - 2)
'Aligns the text to the right
cellValue.Offset(0, 2).HorizontalAlignment = xlRight
End If
An additional "DA" is not being added and I haven't made any other functions to add spaces anywhere. The extra space is not added if adding "DA " is changed to "DA".
I'd prefer not to add another function/sub/something somewhere to search and remove any extra spaces.
What the string is AND what is in front of the string is unknown. It could be numbers, characters, spaces or exactly what I want it to be. For example, it could be "Q-Quincey", "BA Bob", "DA White" etc. I thought that searching through the cell for the string I want (Quincey, Bob, White) and altering the cell as needed would be the best way.
Solution that you all helped me come up with:
If pos > 0 Then
modString = Right(cell, Len(cell) - InStr(cell, pos) - 2)
'Removes anything before the channel name and places it in the last column
cellValue.Offset(0, 2) = modString
'Aligns the last column text to the right
cellValue.Offset(0, 2).HorizontalAlignment = xlRight
cellValue.Offset(0, 2).Font.Size = 8
'Add "DA" to the front of the channel name in the rightmost column
If StartsWith(cell, "DA ") = True Then
cellValue.Replace cell, "DA" & modString
Else
cellValue.Replace cell, "DA " & modString
End If
End If

Answer 1

Maybe this is something you can work with:
Sample data:
Sample code:
Sub Test()
With Sheet1.Range("A1:A4")
.Replace "*quincey", "AD Quincey"
End With
End Sub
Result:

Answer 2

In your examples, it seems you want to replace the first "word" in the string with something else. If that is always the case, the following function, which makes use of Regular Expressions, can do that:
Option Explicit
Function replaceStart(str As String, replWith As String) As String
Dim RE As Object
Set RE = CreateObject("vbscript.regexp")
With RE
.Global = False
.MultiLine = True
.Pattern = "^\S+\W(?=\w)"
replaceStart = .Replace(str, replWith)
End With
End Function
Sub test()
Debug.Print replaceStart("Q-Quincy", "DA ")
Debug.Print replaceStart("BA Bob", "DA ")
Debug.Print replaceStart("DA White", "DA ")
End Sub
The debug.print will -->
DA Quincy
DA Bob
DA White
The regular expression matches everything up to but not including the first "word" character that follows a non-word character. This should be the second word in the string.
A "word" character is anything in the set of [A-Za-z0-9_]
Seems to work on the examples you present.

Answer 3

If you wanted to go about it through a loop you should remove some redundancies in your code. For instance, refering to cell.offset(0,0) doesn't make sense.
I would set the target cells to a range and simply edit that cell with out placing the unwanted strings in another cell.
**EDIT:
I'd try something like this.**
nameiwant = "Quincy"
Set cell = Range("A1")
If InStr(cell, nameiwant) > 0 And Left(cell, 3) <> "DA " Then
cell.Value = "DA " & nameiwant
End If
