I\'d like to select all the rows and columns in a spreadsheet. The macro needs to be dynamic, as the number of columns and rows tend to vary each time the macro would be cal
You need to make these mods to the code
Select with Find as this will give an error if the Find returns nothing. Instead test that the range object Is Not NothingFind can search by row and by column. You need to determine both last row and column to determine the true last used cellRange to set a range from the first cell (A1) to your cell determined with the two Find rangesPls see the code below
If the Find gets a value then it makes a range rng3 from A1 to the last used cell identified by the two Finds.

Sub GetRange()
Dim rng1 As Range
Dim rng2 As Range
Dim rng3 As Range
Set rng1 = Cells.Find("*", [a1], xlFormulas, , xlByRows, xlPrevious)
Set rng2 = Cells.Find("*", [a1], xlFormulas, , xlByColumns, xlPrevious)
If Not rng1 Is Nothing Then
Set rng3 = Range([a1], Cells(rng1.Row, rng2.Column))
MsgBox "Range is " & rng3.Address(0, 0)
'if you need to actual select the range (which is rare in VBA)
Application.Goto rng3
Else
MsgBox "sheet is blank", vbCritical
End If
End Sub
