Hello I need to create a function in Excel using VBA.

I need to pass a range to loop it and perform some calculations.

The idea is use a for next bucle to read all the rows, and analice the diferente columns in it.

The problem is that I don't know how to reference the cells to read it.

Any idea?

At the moment I have this...


Function rangeAnalizer(num As Integer, fecha As Date, rango As Range)
    Dim intNumFilas As Integer
    Dim intNumColumnas As Integer
    Dim celda As Range.Cells
    intNumFilas = rango.Rows.Count
    intNumColumnas = rango.Columns.Count
   
    Dim prueba As Integer
    prueba = celda(1, 1).Item ?????

The easiest way to get a value of a cell in a range passed to a function is:
Dim intNumFilas As Long      'Avoids overflow if more than 32767 rows
Dim x As Variant
For i = 1 To intNumFilas
     x = rango.Cells(i, 1).Value
     'Do stuff with x
Next

Open in new window

You can also pass all the values into a Variant array. This will be considerably faster than looping through the cells.
Dim intNumFilas As Long      'Avoids overflow if more than 32767 rows
Dim v As Variant
For i = 1 To intNumFilas
     v = rango.Value
     'Do stuff with v(i, 1), v(i, 2), etc.
Next

Open in new window
