Avoiding repeated code in worksheet

Can someone help me make this code more professional? I'm trying my best to find something similar, but I wasn't successful.

I want to avoid the repeat of the code for every single value and also I can't find a solution to avoid select. I only get it run when I repeat the code and count rng, rng1, rng2 etc.

```
Sub a()
Dim cell As Range, i As Integer, wks As Worksheet
Dim rng As Range
Dim rng1 As Range
Dim rng2 As Range
Dim rng3 As Range

Set Bereich = Sheets("Tabelle1").Range("B2:B" & Cells(Rows.Count, 1).End(xlUp).Row)

For Each cell In Bereich
If cell.Value = "EURUSD" Then
If Not rng Is Nothing Then
Set rng = Union(rng, Rows(cell.Row))
Else
Set rng = Rows(cell.Row)
End If
End If
Next cell

rng.EntireRow.Select
With Selection
ActiveWorkbook.Sheets.Add After:=Worksheets(Worksheets.Count)
Sheets(ActiveSheet.Name).Name = "EURUSD"
rng.EntireRow.Copy Worksheets("EURUSD").Cells(5, 1)
End With

'--------------------------------------------------------------------------------
Sheets("Tabelle1").Select
For Each cell In Bereich
If cell.Value = "GBPUSD" Then
If Not rng1 Is Nothing Then
Set rng1 = Union(rng1, Rows(cell.Row))
Else
Set rng1 = Rows(cell.Row)
End If
End If
Next cell

rng1.EntireRow.Select
With Selection
ActiveWorkbook.Sheets.Add After:=Worksheets(Worksheets.Count)
Sheets(ActiveSheet.Name).Name = "GBPUSD"
rng1.EntireRow.Copy Worksheets("GBPUSD").Cells(5, 1)

Doing Copy+Paste in your IDE should raise a big red flag and then there should be a neural inhibitor that prevents your left hand from doing it, causing your right hand to move your mouse further down the module and then start typing Private Function...

Now the first thing you need to do before you write any code, is "What is it exactly that I need to be doing?" - don't think in terms of "well I need to loop all cells in that range and check if its value matches a certain specific string, then I need to do [xyz]"; rather, think at one or two levels of abstraction above that, like "well I need to copy all the rows with the same currency code to a new worksheet that's named after the currency code in question".

If I understand what you're doing, you could consider starting with something like this:

Private Function GetRowsForCurrency(ByVal SourceRange As Range, ByVal CurrencyName As String) As Range
    Dim Cell As Range
    Dim Result As New Range

    For Each Cell In SourceRange
        If Cell.Value = CurrencyName Then Set Result = Union(Result, Rows(Cell.Row))
    Next

    Set GetRowsForCurrency = Result
End Function

Then you want to select all these rows and copy them to a new worksheet that you name after the "currency name":

Private Sub CopyToNewWorksheet(ByVal SourceRange As Range, ByVal CurrencyName As String)
    Dim Result As Worksheet
    Set Result = ActiveWorkbook.Sheets.Add(After:=Worksheets(Worksheets.Count))
    Result.Name = CurrencyName
    SourceRange.EntireRow.Copy Result.Cells(5, 1) 'comment why (5,1) here
End Sub

Notice I'm using the Add function's return value, which represents the sheet that was added.

With a function to get the cells and a procedure to copy them to a new sheet, all that's left to do is to call them:

Set Bereich = Sheets("Tabelle1").Range("B2:B" & Cells(Rows.Count, 1).End(xlUp).Row)
CopyToNewWorksheet GetRowsForCurrency(Bereich, "EURUSD"), "EURUSD"
CopyToNewWorksheet GetRowsForCurrency(Bereich, "GBPUSD"), "GBPUSD"
CopyToNewWorksheet GetRowsForCurrency(Bereich, "AUDUSD"), "AUDUSD"
CopyToNewWorksheet GetRowsForCurrency(Bereich, "NZDUSD"), "NZDUSD"

Now this might be made cleaner if you defined and used constants instead of magic strings:

Const EURUSD As String = "EURUSD"
Const GBPUSD As String = "GBPUSD"
...

Couple points

• NEVER call a procedure a() - give it a meaningful name that starts with a verb and that says what the code does. If you can't easily give it a name, it's probably doing too many things.

• Indent your code properly: anything between XXXXX and End XXXXX should be 1 Tab further to the right. If your code starts to look like arrow code, you've got a code smell (follow that link!).

• Those With blocks are absolutely useless - you're never using your with block variable, which means you've set an object reference for no reason.

• If you feel the need to add a number at the end of a variable name, stop right there, take your hands off the keyboard and study what your code is doing that's redundant - refactor as needed.
