Arrays are a variant type variable that you can use in VBA coding to store a list of data. Think of it as a mini-spreadsheet inside of a single variable.

For Each Loop - The For Each Loop will loop through each item in the array.; For Next Loop - The For Next Loop will loop through specified start and end positions of the array (We can use the UBound and LBound Functions to loop through the entire array)
  7. Sub TestArrayValuesSingle() 'Declare the array as a variant array Dim arRng() As Variant 'Declare the integer to store the number of rows Dim iRw As Integer 'Assign range to a the array variable arRng = Range(A1:A10) 'loop through the rows - 1 to 10 For iRw = 1 To UBound(arRng) 'show the result in the immediate window Debug.Print arRng(iRw , 1) Next iRw End Sub . The UBound is used to set.
