As CtrlDot and Leo Guardian says, it is not very acuarate the method, there some files where formats affect the "SpecialCells".

So I used a combination of that plus a While.

Range last = sheet.Cells.SpecialCells(XlCellType.xlCellTypeLastCell, Type.Missing);
Range range = sheet.get_Range("A1", last);
int lastrow = last.Row;
// Complement to confirm that the last row is the last
string textCell= "Existe";
while (textCell != null)
{
 lastrow++;
 textCell = sheet.Cells[lastrow + 1, 1].Value;
}
