1-dimensional array The following macro uses the LBound and Ubound statements to determine the size of the array variable.Sub Macro1() Dim pets(1 To 5, 1 To 3) Msg Box "Lower limit 1-dim: " & LBound(pets, 1) & " Upper limit 1-dim:" & UBound(pets, 1) & " Lower limit 2-dim: " & LBound(pets, 2) & " Upper limit 2-dim: " & UBound(pets, 2) End Sub Sub Macro1() Dim pets(1 To 5, 1 To 3, 1 To 2) Msg Box "Lower limit 1-dim: " & LBound(pets, 1) & " Upper limit 1-dim:" & UBound(pets, 1) & " Lower limit 2-dim: " & LBound(pets, 2) & " Upper limit 2-dim: " & UBound(pets, 2) & " Lower limit 3-dim: " & LBound(pets, 3) & " Upper limit 3-dim: " & UBound(pets, 3) End Sub Sub Macro1() Dim pets() As String Re Dim pets(1 To 5) pets(2) = "dog" Re Dim Preserve pets(1 To UBound(pets) 1) Msg Box "Lbound(pets): " & LBound(pets) & " Ubound(pets): " & UBound(pets) & "pets(2): " & pets(2) End Sub Sub Macro1() Dim pets() As String Re Dim pets(1 To 5, 1 To 2) Re Dim Preserve pets(1 to Ubound(pets,1) , 1 To UBound(pets,2) 1) Msg Box "Lbound(pets,1): " & LBound(pets,1) & " Ubound(pets,1): " & UBound(pets,1) & vb New Line & "Lbound(pets,2): " & LBound(pets,2) & " Ubound(pets,2): " & UBound(pets,2) End Sub Excel is really slow when it comes to manipulating arrays, it is better to try to minimize the number of times you use Re Dim Preserve by guessing how many elements you need.So, to extend the code so that we sum every cell in the range E2: M36 of the active sheet, we could write code as follows: Sub test2() Dim v Data() As Variant Dim r As Integer Dim c As Integer Dim r Total As Variant v Data = Active Sheet. Value r Total = 0 For r = 1 To UBound(v Data, 1) For c = 1 To UBound(v Data, 2) r Total = r Total v Data(r, c) Next Next Debug.

The downside is that you can't change the size of the first dimension using Re Dim Preserve.

Be aware that if you use Transpose with an array that is larger than 65536 in excel 2013 or 2016 no error is shown.

The first argument is the row number and the second is the column number, pets( 3-dimensional arrays It is also possible to have arrays with three dimensions.

The best analogy I can think of is if the first argument is the row number, the second argument is column number, the third argument is then like worksheets.

The example arrays shown above have one dimension but it is possible to have up to 60000 dimensions.

You are probably going to use one or two dimensions most of the time.

VBA provides plenty of methods for traversing Excel workbooks using Cell and Range objects.

It's relatively straightforward to write code that cycles through a worksheet to process cells.

You can use the Re Dim statement to clear all saved array values.

As you can see it returns theses values horizontally.
