How to avoid using Select in Excel VBA

I know that using .Select in Excel VBA is a bad habit, but I don't know how to avoid using it.

Why avoid using .Select, .Activate, etc.?

Two main reasons why .Select.ActivateSelectionActivecellActivesheetActiveworkbook, etc. should be avoided

  1. It slows down your code. Learn speed up Macros.
  2. It is usually the main cause of runtime errors.

Examples of how to avoid .Select, .Activate, etc.

Use Dim'd variables

Dim rng as Range

Set the variable to the required range. There are many ways to refer to a single-cell range:

Set rng = Range("A1")
Set rng = Cells(1, 1)
Set rng = Range("NamedRange")

Or a multi-cell range:

Set rng = Range("A1:B10")
Set rng = Range("A1", "B10")
Set rng = Range(Cells(1, 1), Cells(10, 2))
Set rng = Range("AnotherNamedRange")
Set rng = Range("A1").Resize(10, 2)

You can use the shortcut to the Evaluate method, but this is less efficient and should generally be avoided in production code.

Set rng = [A1]
Set rng = [A1:B10]

All the above examples refer to cells on the active sheet. Unless you specifically want to work only with the active sheet, it is better to Dim a Worksheet variable too:

Dim ws As Worksheet
Set ws = Worksheets("Sheet1")
Set rng = ws.Cells(1, 1)
With ws
    Set rng = .Range(.Cells(1, 1), .Cells(2, 10))
End With

If you do want to work with the ActiveSheet, for clarity it's best to be explicit. But take care, as some Worksheet methods change the active sheet.

Set rng = ActiveSheet.Range("A1")

Again, this refers to the active workbook. Unless you specifically want to work only with the ActiveWorkbook or ThisWorkbook, it is better to Dim a Workbook variable too.

Dim wb As Workbook
Set wb = Application.Workbooks("Book1")
Set rng = wb.Worksheets("Sheet1").Range("A1")

If you do want to work with the ActiveWorkbook, for clarity it's best to be explicit. But take care, as many WorkBook methods change the active book.

Set rng = ActiveWorkbook.Worksheets("Sheet1").Range("A1")

You can also use the ThisWorkbook object to refer to the book containing the running code.

Set rng = ThisWorkbook.Worksheets("Sheet1").Range("A1")

A common (bad) piece of code is to open a book, get some data then close again

This is bad:

Sub foo()
    Dim v As Variant
    Workbooks.Open ("C:\Path\To\SomeClosedBook.xlsx")
    v = ActiveWorkbook.Sheets(1).Range("A1").Value
    ActiveWorkbook.Sheets("SomeSheet").Range("A1").Value = v
End Sub

And it would be better like:

Sub foo()
    Dim v As Variant
    Dim wb1 As Workbook
    Dim wb2 As Workbook
    Set wb1 = Workbooks("SomeAlreadyOpenBook.xlsx")
    Set wb2 = Workbooks.Open("C:\Path\To\SomeClosedBook.xlsx")
    v = wb2.Sheets("SomeSheet").Range("A1").Value
    wb1.Sheets("SomeOtherSheet").Range("A1").Value = v
End Sub

Pass ranges to your Subs and Functions as Range variables:

Sub ClearRange(r As Range)
End Sub

Sub MyMacro()
    Dim rng As Range
    Set rng = ThisWorkbook.Worksheets("SomeSheet").Range("A1:B10")
    ClearRange rng
End Sub

Directly work with the relevant objects:

Consider this code

Selection.Value = "Blah"
Selection.NumberFormat = "@"

This code can also be written as

With Sheets("Sheet1").Range("A1")
    .Value = "Blah"
    .NumberFormat = "@"
End With

If required declare your variables. The same code above can be written as:

Dim ws As Worksheet
Set ws = Sheets("Sheet1")
With ws.Range("A1")
    .Value = "Blah"
    .NumberFormat = "@"
End With

You should also apply Methods (such as Find and Copy) to variables:

Dim rng1 As Range
Dim rng2 As Range
Set rng1 = ThisWorkbook.Worksheets("SomeSheet").Range("A1:A10")
Set rng2 = ThisWorkbook.Worksheets("SomeSheet").Range("B1:B10")
rng1.Copy rng2

If you are looping over a range of cells it is often better (faster) to copy the range values to a variant array first and loop over that:

Dim dat As Variant
Dim rng As Range
Dim i As Long

Set rng = ThisWorkbook.Worksheets("SomeSheet").Range("A1:A10000")
dat = rng.Value  ' dat is now array (1 to 10000, 1 to 1)
For i = LBound(dat, 1) To UBound(dat, 1)
    dat(i, 1) = dat(i, 1) * 10 ' Or whatever operation you need to perform
rng.Value = dat ' put new values back on sheet
